General Description

The 1-to-9 fanout buffer is designed for low noise clock distribution.

It is intended to generate relatively square wave outputs with rise/fall times < 100 ps.

The low skew and jitter outputs of the HMC987LP5E, combined with its fast rise/fall times, leads to controllable low-noise switching of downstream circuits such as mixers, ADCs/DACs or SERDES devices.

Overview

Clock Distribution - SMT v03.1112 Typical Applications The is suitable for: • SONET, Fibre Channel, GigE Clock Distribution • ADC/DAC Clock Distribution • Low Skew and Jitter Clock or Data Fanout • Wireless/Wired.
