HMC765LP6CE
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.
