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
Chan-
nel can optionally be synchronous to an external sys-
tem 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.
