HMC1032LP6GE

Clock Generators, PLLs, Frequency Synthesizers Overview

The HMC1032LP6GE is a low-noise, wide-band clock generator IC featuring a fractional-N Phase Locked Loop (PLL) with an integrated Voltage Controlled Oscillator (VCO). It provides differential clock outputs in the 125 MHz to 350 MHz range. The device incorporates a low-noise Phase Detector and Delta-Sigma Modulator capable of operating at up to 100 MHz, enabling wider loop bandwidths and excellent spectral performance. Key electrical specifications include a typical RMS jitter of 75 fs, a phase noise floor of -165 dBc/Hz, and a Figure of Merit (FoM) of -227 dBc/Hz. It operates on 3.3V digital supplies and 5V analog supplies within a temperature range of -40°C to +85°C.
