General Description
The HMC765LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) with an Integrated Voltage
Controlled Oscillator (VCO). The input reference frequency range is 100 kHz to 220 MHz while the advanced delta-
sigma modulator design in the fractional PLL allows both ultra-ne step sizes and very low spurious products. The
highly integrated structure provides excellent phase noise performance over temperature, shock and process. The
HMC765LP6CE is packaged in a leadless QFN 6 x 6 mm surface mount package. The output power is 13 dBm typical,
making the HMC765LP6CE ideal for driving the LO port of many of Hittite’s Hi Linearity and I/Q mixer products.
For theory of operation and register map refer to the “PLLs w/ Integrated VCO - Microwave VCOs” Operating Guide.
To view the Operating Guide, please visit www.hittite.com and choose HMC765LP6CE from the “Search by Part
Number” pull down menu.

[1] This pin is not connected internally, however, this pin must be connected to GND to maintain product family pin for pin compatibility.
[2] This pin is not connected internally, however, this pin must be connected to Vcc to maintain product family pin for pin compatibility.
[3] BIAS ref voltage (pin 20) cannot drive an external load, and must be measured with a 10 GOhm meter such as Agilent 34410A; a typical
10 Mohm DVM will read erroneously.

FRACTIONAL-N PLL WITH
INTEGRATED VCO, 7.8 - 8.8 GHz
Evaluation PCB
The circuit board used in the application should use RF circuit design techniques. Signal lines should have
50 Ohm impedance while the package ground leads and exposed 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. The evaluation circuit board shown is available from Hittite upon request.
