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. Two capacitors with 10 F and 0.01 F values must be connected to the "PLL Vref" 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).

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 14 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.

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 Vref" 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.

Data and Clock Timing Requirement 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. Figure 11. Enable Timing Requirement 50% Clk tsuEC First Clock trec 50% EN 50% Last Clock 50% Previous Data Latched MOTOROLA ANALOG IC DEVICE DATA MC13109 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. Figure 12.

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.

In Standby and Inactive Modes, "PLL Vref" 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 s) 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. Figure 22.

"MPU Clock Out" remains active for a minimum of one count of reference counter after "CD Out/Hardware Interrupt" pin goes high 20 MOTOROLA ANALOG IC DEVICE DATA MC13109 "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).

In order to minimize radiated noise, a 1.0 k 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. Figure 25.

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 Test 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.
