Direct Rambus™ Clock Generator Lite  
General Description  
Features  
TM  
Compatible with all Direct Rambus based ICs  
ICS9219 is a High-speed clock generator providing 400 or  
533 MHz differential clock source for direct Rambus  
memory system. ICS9219 takes a crystal as an input  
reference source, and produces the differential output  
clock required for the Rambus channel. ICS9219 provides  
a solution for a broad range of Direct Rambus memory  
applications. ICS9219 can be used in single or dual  
Rambus channels. An additional LVCMOS output, which  
provides a reference clock at the crystal frequency for the  
other system blocks is also included.  
Provides differential clock source for direct  
Rambus memory system with 1GHz data transfer  
rate capability  
Cycle to Cycle jitter is less than 100ps  
3.3V + 4% supply  
LVCMOS REF clock @ crystal frequency  
Output edge rate control to minimize EMI
