General Description
The HMC3716LP4E is a digital phase frequency detector which operates from 10 to 1300MHz. 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 floor 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 amplifier, the HMC3716LP4E 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.

All data shown is typical and actual performance may vary depending upon implementation.
Phase Noise data taken utilizing 2-unit PLL cancellation method with VCO ≥ 2400MHz and healthy power level.
Only one PFD output will be active with a forced frequency difference, depending upon which input frequency is higher.
Without oscilloscope bandwidth limiting, there will be narrow pulses on NU, ND, & LD, at the input frequencies.
These pulses may create spectral content, which is normally surpressed with the loop filter and lock detect filter.

HMC3716LP4E
v02.0316
HBT DIGITAL PHASE FREQUENCY DETECTOR
10 - 1300MHz
The phase frequency detector functionality of the HMC3716LP4E 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.
INVERT 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 filter op-amp inputs were swapped.
A logic “LOW” on this pin will configure 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.
Lock Detect Functionality
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 filter.
Since the pin will produce very narrow pulses at each zero crossing of the REF and VCO input signals, filtering 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 filtered output voltage will be “HIGH”.
Below is an example of an RC filter for the lock detect pin. The value of resistor “R” should be greater than 100Ω
to limit any surge current from flowing when the output transistor is “ON”. The value of capacitor “C” should be
selected such that the filter cutoff is much less than the REF frequency, but not excessively large (slow) that it will
inhibit detection of lock status.

A diffential op-amp loop filter 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 filter synthesis can be performed using a variety of simulation tools. Below is
an example of a third-order filter produced with the listed PLL parameters for loop bandwidth, etc.
