Functional Description
The CY28354-400 is a 2.5V buffer designed to distribute
high-speed clocks in PC applications. The part has 24 outputs
to support four unbuffered DDR DIMMS. The CY28354-400
can be used in conjunction with CY28326 similar clock synthe-
sizer for the PTT880 and KTT880 chipsets.
The CY28354-400 also includes an SMBus interface which
can enable or disable each output clock. On power-up, all
output clocks are enabled.
