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