CDCD5704 - Texas Instruments

CDCD5704 CLOCK GENERATOR

The CDCD5704 clock generator provides the necessary clock signals to support an XDR memory subsystem and Redwood logic interface using a reference clock input with or without spread-spectrum modulation. Contained in a 28-pin TSSOP package that includes four differential clock outputs, the CDCD5704 provides an off-the-shelf solution for a broad range of high-.
