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).
