CDCM7005 - Texas Instruments

CDCM7005 3.3-V High Performance Clock Synchronizer and Jitter Cleaner

The CDCM7005 is a high-performance, low phase noise and low skew clock synchronizer that synchronizes a VCXO (voltage controlled crystal oscillator) or VCO (voltage controlled oscillator) frequency to one of the two reference clocks. The programmable pre-divider M and the feedbackdividers N and P give a high flexibility to the frequency ratio of the referenc.

Features

•1 High Performance LVPECL and LVCMOS PLL Clock Synchronizer
