Functional Description
The CY2318BNZ is a 3.3V buffer designed to distribute
high-speed clocks in PC applications. The part has 18 outputs,
16 of which can be used to drive up to four SDRAM 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
The CY2318BNZ can be used in conjunction with the CY2280,
CY2281, CY2282 or similar clock synthesizer for a complete
Pentium II motherboard solution.
The CY2318BNZ also includes an SMBus interface which can
enable or disable each output clock. On power-up, all output
clocks are enabled (internal pull up). A separate Output Enable
pin facilitates testing on ATE.
