FeaturesTypical Applications
Ultra Low SSB Phase Noise Floor:
-151dBc/Hz @ 10kHz offset @ 100MHz
Integrated Output Resistors
Improved Input Sensitivity
Lock Detect and Invert Functionality
24-Pin 4 x 4mm SMT Package
The HMC4069LP4E is an Integer-N synthesizer which incorporates a 10 to 1300MHz digital phase-frequency detector
with a 10 to 2900MHz 5-bit frequency counter. It is intended for use in low phase noise synthesizer applications.
The combination of high frequency of operation along with its ultra low phase noise oor make possible synthesizers
with wide loop bandwidth and low N resulting in fast switching and very low phase noise. When used in conjunction
with a differential loop amplier, the HMC4069LP4E generates output voltages that can be used to phase lock a VCO
to a reference oscillator.
The device is packaged in a 24-pin, 4 x 4mm leadless QFN surface mount package with an exposed ground paddle
for improved RF and thermal performance.
The HMC4069LPE is ideal for:
• Point-to-Point Radios
• Satellite Communication Systems
• Military Applications
• Sonet Clock Generation

The LD pin is an open collector pulsed output transistor. It requires an external 1k pull up resistor to Vcc (5V), as
well as a simple RC lter.
Since the pin will produce very narrow pulses at each zero crossing of the REF and VCO input signals, ltering is
necessary to create an average voltage which can be used to drive an LED or system input logic. When the device
is “LOCKED”, that transistor will effectively be “OFF”, and the ltered output voltage will be “HIGH”.
Below is an example of an RC lter for the lock detect pin. The value of resistor “R” should be greater than 100Ω
to limit any surge current from owing when the output transistor is “ON”. The value of capacitor “C” should be
selected such that the lter cutoff is much less than the REF frequency, but not excessively large (slow) that it will
inhibit detection of lock status.
Lock Detect Functionality
The INV pin effectively swaps the REF and VCO input signals, such that the NU and ND pin responses are
swapped. This has the advantage of easily correcting a layout issue if the loop lter op-amp inputs were swapped.
A logic “LOW” on this pin will congure the device for normal operation, and a logic “HIGH” cause the input signals
to swap. The evaluation board has a 10kΩ resistor pull up resistor to 5V. A jumper must be installed connecting the
INV pin to ground for normal operation.
INVERT Functionality
PFD Functionality
The phase frequency detector functionality of the HMC4069LP4E is such that it compares the rising edge the two
input signals (REF / VCO). This information is then used to pulse the ND and NU outputs depending upon which
input signal is greater in frequency.
Under normal operation the ND pin will be active when VCO frequency is greater than the REF frequency; NU would
remain constant. Conversly, when the VCO frequency is lower than the REF frequency, then NU would be active
and ND would remain constant. Here, the term “active” means that the output will on average, vary between 3 - 5V,
and the term “remain constant” means that the output will remain at approximately 5V.

A diffential op-amp loop lter is required in order to integrate the ND and NU pulses into a usable tune voltage to
drive the oscillator in a PLL. The loop lter synthesis can be performed using a variety of simulation tools. Below is

The circuit board used in the application should use RF circuit design techniques. Signal lines should
have 50Ω impedance while the package ground leads and backside ground paddle should be connected
directly to the ground plane similar to that shown. A sufficient number of via holes should be used to
connect the top and bottom ground planes.
