Dual Direct Rambus Clock Generator
Features
Differential clock source for Direct Rambus memory subsystem for up to 1.6-Gb/s serial data transfer rate Provide synchronization flexibility: the Rambus Channel can optionally be synchronous to an external system or processor clock Power managed output allows Rambus Channel clock to be turned off to minimize power consumption for mobile applications Works with Cypress CY2210-2, CY2210-3, CY2215, W133, W158, W159, W161, and W167B to support Intel architecture platforms Low-power CMOS design packaged in a 28-pin, 173-mil TSSOP package
Overview
The Cypress W234 provides dual channel differential clock signals for a Direct Rambus memory subsystem. It includes signals to synchronize the Direct Rambus Channel clock to an external system clock but can also be used in systems that do not require synchronization of the Rambus clock.
