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
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.
processors. The CY2310BNZ can be used in
