CDCD5704 Datasheet Clock Generator

Manufacturer: Texas Instruments

Overview: .ti. Rambus™ XDR™ CLOCK GENERATOR CDCD5704 SCAS823 – DECEMBER.

General 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.

The block diagram shows the major ponents of the CDCD5704, which include a phase-locked loop, a bypass multiplexer, and four differential output buffers (CLK0 to CLK3).

Key Features

  • High-Speed Clock Support: 300-MHz.
  • 667-MHz Clock Source for XDR Memory Subsystems and Redwood Logic Interface.
  • Quad (Open-Drain) Differential Output Drivers.
  • Spread-Spectrum Compatible Clock Input Can Be Distributed to Minimize EMI.
  • Differential or Single-Ended Reference Clock Input of 100 MHz or 133 MHz.
  • Serial Interface Features: Programmable Frequency Multiplier, Select Any One to Four Outputs and Mode of Operation.
  • Supports Freque.
