Texas Instruments CDCU877/CDCU877A 1.8-V Phase Lock Loop Clock Driver Datasheet
The CDCU877 is a Zero-delay buffer designed to distribute a differential clock input pair to ten differential pairs of clock outputs and one feedback output. It features low jitter and skew specifications suitable for Double Data Rate (DDR II) applications.
The device operates from an operating frequency range of 10 MHz to 400 MHz and supports spread spectrum clocking (SSC). It is available in a 52-ball BGA package or a 40-pin MLF package.
