General Description

The ICS9214 clock generator provides the necessary clock signals to support the Rambus XDRTM memory subsystem and Redwood logic interface. The clock source is a reference clock that may or may not be modulated for spread spectrum. The ICS9214 provides 4 differential clock pairs in a space saving 28-pin TSSOP package and provides an off-the-shelf high-performance interface solution.

Features

? 400 – 500 MHz clock source

? 4 open-drain differential output drives with short term jitter < 40ps

? Spread spectrum compatible

? Reference clock is differential or single-ended, 100 or 133 MHz

? SMBus programmability for:

- frequency multiplier

- output enable

- operating mode

? Supports frequency multipliers of: 3, 4, 5, 6, 8, 9/2, 15/2 and 15/4

? Support systems where XDR subsystem is asynchronous to other system clocks

? 2.5V power supply
