Texas Instruments  CDCE421AEVM

CDCE421AEVM is the evaluation module for CDCE421A. CDCE421A is a highly versatile, <1ps rms ultra low-jitter frequency synthesizer that takes a low-frequency crystal or LVCMOS input and generates clock output from 10MHz to 1100MHz with fully integrated silicon VCO. The output is selectable among LVPECL, LVDS, or 2 LVCMOS. It is intended to replace high frequency XO for a variety of wireline and data communication applications.
