Features
Differential clock source for Direct Rambus
memory
subsystem for up to 800-MHz 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, W133, W158, W159, W161,
and W167 to support Intel architecture platforms
Low-power CMOS design packaged in a 24-pin, 150-mil
SSOP package
Overview
The Cypress W134M/W134S provides the 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.
