HMC765LP6CE
v03.0411
FRACTIONAL-N PLL WITH
INTEGRATED VCO, 7.8 - 8.8 GHz
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-fine 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.
