APPROVED PRODUCT

C9822

Direct Rambus III Clock Generator

Product Features

Product Description

•

High Speed Clock support - provides a 267 to

400MHz differential clock source for Direct

Rambus memory systems for an 1.6 GbPS data

transfer rate

Synchronization Flexibility - provides signals to

synchronize the clock domains of the Rambus

Channel with an external system or processor

clock, provided by C9801, C9812, C9830, C9840,

C9850, C9851, and C9853.

Power Management Support permits channel

clocks to be enabled and disabled as required

Supports Independent Channel Clocking

24 pin 150 mil SSOP Package

The C9822 is a Rambus compliant DRCG clock

synchronizer. It contains a Phase Locked Loop that

provides complimentary Rambus

memory clocks.

Included in its functionality is the control logic to phase

and frequency synchronizing the device’s output clocks

with the system reference clock. Power management

logic is also provided for Mobile application and green

PC functionality. Also included are separate power pins

for each internal functional block so as to minimize

interaction of these sections with each other and thus

maximize the device performance.
