Direct Rambus™ Clock Generator
Description
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.
