HMC764LP6CE
FRACTIONAL-N SYNTHESIZER WITH
INTEGRATED VCO, 7.3 - 8.2 GHz
General Description
The HMC764LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) Frequency Synthesizer 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 synthesizer 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 HMC764LP6CE is packaged in a leadless QFN 6x6 mm surface mount package. The output
power is 15 dBm typical, making the HMC764LP6CE 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.
