Description
The CY2310BNZ is a 3.3V buffer designed to distribute
high-speed clocks in mobile PC applications. The part has ten
outputs, eight of which can be used to drive up to four SDRAM
SO-DIMMs, and the remaining can be used for external
feedback to a PLL. The device operates at 3.3V and outputs
can run up to 100 MHz, thus making it compatible with
Pentium II
processors. The CY2310BNZ can be used in
conjunction with the CY2281 or similar clock synthesizer for a
full Pentium II motherboard solution.
The CY2310BNZ also includes an SMBus interface that can
enable or disable each output clock. On power-up, all output
clocks are enabled. A separate Output Enable pin facilitates
testing on ATE.
