Pre–Amplifier/Expander/Rx Mute/Volume Control (See Figure 4)
The Pre–Amplifier is an inverting rail–to–rail output swing
operational amplifier with the non–inverting input terminal
connected to the internal VB half supply reference. External
resistors and capacitors can be connected to set the gain and
frequency response. The expander analog ground is set to
the half supply reference so the input and output swing
capability will increase as the supply voltage increases. The
volume control can be adjusted through the MPU interface.
The “Rx Audio In” input signal is ac coupled.
(Test Conditions: VCC = 2.6 V, TA = 25°C, fin = 1.0 kHz, Set External Pre–Amplifier R’s for Gain of 1, Volume Control = (0111).)

Compressor/ALC/Tx Mute/Limiter (See Figure 5)
The compressor analog gound is set to the half supply
reference so the input and output swing capability will
increase as the supply voltage increases. The “C In” input is
ac coupled. The ALC (Automatic Level Control) provides a
soft limit to the output signal swing as the input voltage
increases slowly (i.e., a sine wave is maintained). The Limiter
circuit limits rapidly changing signal levels by clipping the
signal peaks. The ALC and/or Limiter can be disabled
through the MPU serial interface.

resistors and capacitors can be connected to set the gain and

Tx Audio Path Recommendation
The recommended configuration for the Tx Audio path
includes setting the Microphone Amplifier gain to 16 dB using
the external gain setting resistors and setting the Splatter
Amplifier gain to 9.0 dB using the external gain setting
resistors. With these gain values, the total Tx Path transfer
characteristic is shown in Figure 7.
PLL Voltage Regulator
The PLL supply voltage is regulated to a nominal of 2.2 V.
The “VCC Audio” pin is the supply voltage for the internal
voltage regulator. The “PLL Vref” pin is the 2.2 V regulated
output voltage. T wo capacitors with 10 µF and 0.01 µF values
must be connected to the “PLL V ref” pin to filter and stabilize
this regulated voltage. The voltage regulator provides power
for the 2nd LO, Rx and Tx PLL’s, and MPU Interface. The
voltage regulator can also be used to provide a regulated
supply voltage for external IC’s. Rx and Tx PLL loop
performance are independent of the power supply voltage
when the voltage regulator is used. The voltage regulator
requires about 200 mV of “headroom”. When the power
supply decreases to within about 200 mV of the output
voltage, the regulator will go out of regulation but the output
voltage will not turn off. Instead, the output voltage will
maintain about a 200 mV delta to the power supply voltage as
the power supply voltage continues to decrease. The “PLL
Vref” pin can be connected to “VCC Audio” by the external
wiring if voltage higher than 2.2 V is required. But it should
not be connected to other supply except “VCC Audio”. The
voltage regulator is “on” in the Active and Rx modes. In the
Standby and Inactive modes, the voltage regulator is turned
off to reduce current drain and the “PLL Vref” pin is internally
connected to “VCC Audio” (i.e., the supply voltage is
maintained but is now unregulated).
(Test Conditions: VCC = 2.6 V, TA = 25°C.)

Power Supply Voltage
This circuit is used in a cordless telephone handset and
base unit. The handset is battery powered and can operate
on two ro three NiCad cells or on 5.0 V power.
PLL Frequency Synthesizer General Description
Figure 8 shows a simplified block diagram of the
programmable universal dual phase locked loop (PLL). This
dual PLL is fully programmable thorugh the MCU serial
interface and supports most country channel frequencies
including USA (25 ch), France, Spain, Australia, Korea, New
Zealand, U.K., Netherlands and China (see channel
frequency tables in Appendix A).
The 2nd local oscillator and reference divider provide the
reference frequency for the Rx and Tx PLL loops. The
programmed divider value for the reference divider is
selected based on the crystal frequency and the desired Rx
and Tx reference frequency values. Additional divide by 25
and divide by 4 blocks are provided to allow for generation of
the 1.0 kHz and 6.25 kHz reference frequencies required for
the U.K. The 14–bit Tx counter is programmed for the desired
transmit channel frequency. The 14–bit Rx counter is
programmed for the desired first local oscillator frequency. All
counters power up in the proper default state for USA
channel #6 and for a 10.24 MHz reference frequency crystal.
Internal fixed capacitors can be connected to the tank circuit
of the 1st LO through microprocessor control to extend the
sensitivity of the 1st LO for U.S. 25 channel operation.

PLL I/O Pin Specifications
The 2nd LO, Rx and Tx PLL ’s and MPU serial interface are
normally powered by the internal voltage regulator at the
“PLL Vref” pin. The “PLL Vref” pin is the output of a voltage
regulator which is powered from the “VCC Audio” power
supply pin. Therefore, the maximum input and output levels
for most PLL I/O pins (LO2 In, LO2 Out, Rx PD, Tx PD, Tx
VCO) is the regulated voltage at the “PLL V ref” pin. The ESD
protection diodes on these pins are also connected to “PLL
Vref”. Internal level shift buffers are provided for the pins
(Data, Clk, EN, Clk Out) which connect directly to the
microprocessor. The maximum input and output levels for
these pins is VCC. Figure 9 shows a simplified schematic of
the PLL I/O pins.

Microprocessor Serial Interface
The “Data”, “Clk”, and “EN” pins provide an MPU serial
interface for programming the reference counters, the
transmit and receive channel divider counter and various
control functions. The “Data” and “Clk” pins are used to load
data into the shift register. Figure 10 shows “Data” and “Clk”
pin timing. Data is clocked on positive clock transitions.

After data is loaded into the shift register, the data is
latched into the appropriate latch register using the “EN” pin.
This is done in two steps. First, an 8–bit address is loaded
into the shift register and latched into the 8–bit address latch
register. Then, up to 16–bits of data is loaded into the shift
register and latched into the data latch register specified by
the address that was previously loaded. Figure 11 shows the
timing required on the EN pin. Latching occurs on the
negative EN transition.

MOTOROLA ANALOG IC DEVICE DATA
The state of the EN pin when clocking data into the shift
register determines whether the data is latched into the
address register or a data register. Figure 12 shows the
address and data programming diagrams. In the data
programming mode, there must not be any clock transitions
when “EN” is high. The clock can be in a high state (default
high) or a low state (default low) but must not have any
transitions during the “EN” high state. The convention in
these figures is that latch bits to the left are loaded into the
shift register first.

The MPU serial interface is fully operational within 100 µs
after the power supply has reached its minimum level during
power–up (See Figure 13). The MPU Interface shift registers
and data latches are operational in all four power saving
modes; Inactive, Standby, Rx, and Active Modes. Data can
be loaded into the shift registers and latched into the latch
registers in any of the operating modes.

Status Out
This is a digital output which indicates whether the latch
registers have been reset to their power–up default values.
Latch power–up default values are given in Figure 32. If there
is a power glitch or ESD event which causes the latch
registers to be reset to their default values, the “Status Out”
pin will indicate this to the MPU so it can reload the correct
information into the latch registers.

Data Registers
Figure 15 shows the data latch registers and addresses
which are used to select each of these registers. Latch bits to
the left (MSB) are loaded into the shift register first. The LSB
bit must always be the last bit loaded into the shift register.
“Don’t care” bits can be loaded into the shift register first if
8–bit bytes of data are loaded.

The “LO2 In” and “LO2 Out” pins form a reference oscillator
when connected to an external parallel–resonant crystal. The
reference oscillator is also the second local oscillator for the
RF Receiver. Figure 16 shows the relationship between
different crystal frequencies and reference frequencies for
cordless phone applications in various countries.

Reference Counter
Figure 17 shows how the reference frequencies for the Rx
and Tx loops are generated. All countries except U.K. require
that the Tx and Rx reference frequencies be identical. In this
case, set “U.K. Base Select” and “U.K. Handset Select” bits
to “0”. Then the fixed divider is set to “1” and the Tx and Rx
reference frequencies will be equal to the crystal oscillator
frequency divided by the programmable reference counter
value. The U.K. is a special case which requires a different
reference frequency value fo Tx and Rx.
For U.K. base operation, set “U.K. Base Select” to “1”. For
U.K. handset operation, set “U.K. Handset Select” to “1”. The
Netherlands is also a special case since a 2.5 kHz reference
frequency is used for both the Tx and Rx reference and the
total divider value required is 4096 which is larger than the
maximum divide value available from the 12–bit reference
divider (4095). In this case, set “U.K. Base Select” to “1” and
set “U.K. Handset Select” to “1”. This will give a fixed divide
by 4 for both the Tx and Rx reference. Then set the reference
divider to 1024 to get a total divider of 4096.
Mode Control Register
Power saving modes, mutes, disables, volume control,
and microprocessor clock output frequency are all set by the
Control Register. Operation of the Control Register is
explained in Figures 18 through 25.

Power Saving Operating Modes
When the MC13109 is used in a handset, it is important to
conserve power in order to prolong battery life. There are five
modes of operation; Active, Rx, Standby, Interrupt and
Inactive. In Active Mode, all circuit blocks are powered. In Rx
mode, all circuitry is powered down exept for those circuit
sections needed to receive a transmission from the base. In
the Standby and Interrupt Modes, all circuitry is powered
down except for the circuitry needed to provide the clock
output for the microprocessor . In Inactive Mode, all circuitry is
powered down except the MPU interface. Latch memory is
maintained in all modes. Figure 20 shows the control register
bit values for selection of each power saving mode and
Figure 21 show the circuit blocks which are powered in each
of these operating mode.

NOTE: 1.In Standby and Inactive Modes, “PLL V ref” remains powered but is not regulated. It will fluctuate with VCC.
Inactive Mode Operation and Hardware Interrupt
In some handset applications it may be desirable to power
down all circuitry including the microprocessor (MPU). First
put the MC13109 into the Inactive mode, which turns off the
MPU Clock Output (see Figure 22), and then disable the
microprocessor. In order to give the MPU adequate time to
power down, the MPU Clock output remains active for a
minimum of one reference counter cycle (about 200 µs) after
the command is given to switch into the “Inactive” mode. An
external timing circuit should be used to initiate the turn–on
sequence. The “CD Out” pin has a dual function. In the Active
and Rx modes it performs the carrier detect function. In the
Standby and Inactive modes the carrier detect circuit is
disabled and the “CD Out” pin is in a “High” state due to the
external pull–up resistor. In the Inactive mode the “CD Out”
pin is the input for the hardware interrupt function. When the
“CD Out” pin is pulled “low” by the external timing circuit, the
MC13109 swtiches from the Inactive to the Interrupt mode
thereby turning on the MPU Clock Output. The MPU can then
resume control of the combo IC. The “CD Out” pin must
remain low until the MPU changes the operating mode from
Interrupt to Standby, Active or Rx modes.

“Clk Out” Divider Programming
The “Clk Out” pin is derived from the 2nd local oscillator
and can be used to drive a microprocessor, thereby reducing
the number of crystals required. Figure 23 shows the
relationship between the crystal frequency and the clock
output for different divider values. Figure 24 shows the “Clk
Out” register bit values.

MPU “Clk Out“ Power–Up Default Divider Value
The power–up default divider value is “divide by 10”. This
provides an MPU clock of about 1.0 MHz after initial
power–up. The reason for choosing this relatively low clock
frequency after intial power–up is that some microprocessors
that operate down to a 2.0 V power supply have a maximum
clock frequency fo 1.0 MHz. After initial power–up, the MPU
can change the clock divider value to set the clock to the
desired operating frequency. Special care has been taken in
the design of the clock divider to ensure that the transition
between one clock divider value and another is “smooth”
(i.e., there will be no narrow clock pulses to disturb the MPU).
MPU “Clk Out” Radiated Noise on Circuit Board
The clock line running between the MC13109 and the
microprocessor has the potential to radiate noise which can
cause problems in the system especially if the clock is a
square wave digital signal with large high frequency
harmonics. In order to minimize radiated noise, a 1.0 kΩ
resistor is included on–chip in–series with the “Clk Out” output
driver . A small capacitor can be connected to the “Clk Out” line
on the PCB to form a single pole low pass filter. This filter will
significantly reduce noise radiated from the “Clk Out” line.
Volume Control
The volume control can be programmed in 2.0 dB gain
steps from –14 dB to +16 dB. The power–up default value is
0 dB.

MOTOROLA ANALOG IC DEVICE DATA
Auxiliary Register
The auxiliary register contains a 3–bit 1st LO Capacitor
Selection latch and a 4–bit Test Mode latch. Operation of
these latch bits are explained in Figures 28, 29 and 30.

First Local Oscillator Capacitor Selection for 25
Channel U.S. Operation
There is a very large frequency difference between the
minimum and maximum channel frequencies in the proposed
25 Channel U.S. standard. The sensitivity of the 1st LO is not
large enough to accommodate this large frequency variation.
Fixed capacitors can be connected across the 1st LO tank
circuit to change the 1st LO sensitivity. Internal switches and
capacitors are provided to enable microprocessor control
over internal fixed capacitor values. Figure 29 shows the
schematic of the 1st LO tank circuit. Figure 30 shows the
latch control bit values.
The internal varactor temperature coefficient is 1800 ppm/°C
(CO = 8.9 pF at 25°C, Vcap control voltage = 1.2 V, Freq =
36 MHz). Customer is suggested to use a negative
temperature coefficient capacitor in 1st LO tank circuit when
the whole operating temperature range of –40 to +85°C is
considered.

NOTE: To determine the correct output, look at the lower 8 bits in the Rx or Tx register (Divisor (7;0). If the value of the divisor is > 16, then the output divisor
value is Divisor (7;2) (the upper 6 bits of the divisor). If Divisor (7;0) < 16 and Divisor (3;2) > = 2, then output divisor value is Divisor (3;2) (bits 2 and 3
of the divisor). If Divisor (7;0) < 16 and Divisor (3;2) < 2, then output divisor value is (Divisor (3;2) + 60).
Test Modes
Tes t Mode Control latch bits enable independent testing
of internal counters and set AGC Gain Options. In test
mode, the “Tx VCO” input pin is multiplexed to the input of
the counter under test and the output of the counter under
test is multiplexed to the “Clk Out” output pin so that each
counter can be individually tested. Make sure test mode bits
are set to “0” for normal operation. Test mode operation is
described in Figure 31. During normal operation and when
testing the Tx Prescaler, the “Tx VCO” input can be a
minimum of 200 mVpp at 80 MHz and should be ac coupled.
For other test modes, input signals should be standard logic
levels of 0 to 2.2 V and a maximum frequency of 16 MHz.
Power–Up Defaults for Control and Counter Registers
When the IC is first powered up, all latch registers are
initialized to a defined state. The MC13109 is initially placed in
the Rx mode with all mutes active and nothing disabled. The
reference counter is set to generate a 5.0 kHz reference
frequency from a 10.24 MHz crystal. The MPU clock output
divider is set to 10 to give the minimum clock output frequency .
The Tx and Rx latch registers are set for USA Channel
Frequency #21. Figure 32 shows the initial power–up states
for all latch registers.
