APPLICATIONS
XDR Memory Subsystem and Redwood Logic
Interface
DESCRIPTION
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-performance interface applications.

SCAS823–DECEMBER 2006
Rambus XDR CLOCK GENERATOR
The block diagram shows the major components of the CDCD5704, which include a phase-locked loop, a
bypass multiplexer, and four differential output buffers (CLK0 to CLK3). All four outputs can be disabled by a
logical low at the input of the EN pin. An output is enabled when EN is high and a value of 1 is in its serial
interface register (RegA–RegD).
The PLL receives a reference clock input signal, REFCLK, and outputs a clock signal at a frequency equal to the
input frequency times the multiplication factor. The PLL output clock signal is fed to the differential output buffers
to drive the enabled clocks. Disabled outputs are set to high impedance.
