General Description
The ICS9222-01 is a High-speed clock generator providing two channels up to 450 MHz differential clock source for direct Rambus_memory system. It includes two independent DDLL’s (Distributed Delay locked loop) and phase detection mechanisms to synchronize eachdirect Rambus_ channel clock to an external system clock. ICS9222-01 provides a solution for a broad range of Direct Rambus memory applications. The device works in conjunction with the ICS964S101, as well as 9250-22 and others (depending on chipset).

FEATUREs
• Compatible with all Direct Rambus™ based ICs
• Up to 450 MHz differential clock source for direct
   Rambus™ memory system
• Cycle to cycle jitter is less than 100 ps
• 3.3 ± 5% supply
• Synchronization flexibility: Supports systems that need
   clock domains of Rambus channel to synchronize with
   system or processor clock, or systems that do not
   require synchronization of the Rambus clock to another
   system clock.
• Excellent power management support
• REFCLK input is from the main clock generator such as
   a 9250-22.
