HMC1032LP6GETR

PLL Clock Generator Single 125 to 350MHz 40Pin QFN T/R

Product Details

The HMC1032LP6GE is a low-noise, wide-band clock generator IC with a fractional-N Phase Locked Loop PLL that features an integrated Voltage Controlled Oscillator VCO. The device provides differential clock outputs between 125 and 350 MHz range. The HMC1032LP6GE features low noise Phase Detector PD and Delta-Sigma modulator, capable of operating at up to 100 MHz, permit wider loop-bandwidths with excellent spectral performance.

The HMC1032LP6GE features industry leading phase noise and jitter performance, across the operating range, that enable it to improve link level jitter performance, Bit-Error-Rates BER and eye diagram metrics. The superior noise floor <-165 dBc/Hz makes the HMC1032LP6GE an ideal source for a variety of applications –such as clock references for high speed data converters, physical layer devices PHY, serializer/deserializer SERDES circuits, FPGAs and processors. The HMC1032LP6GE can also be used as reference clock and LO for 1G/10G Ethernet line cards as well as jitter attenuation and frequency translation.

The differential output of the HMC1032LP6GE includes a 2-bit output amplitude control which may be set via the SPI serial programming interface, and an output Mute function. The Delta-Sigma Modulator of the HMC1032LP6GE features Hittite’s Exact Frequency Mode, which enables users to generate output frequencies with close to 0 Hz frequency error.
