The CY2310ANZ is a 3.3V buffer designed to distribute high-speed clocks in mobile PC applications. The part has 10 outputs, 8 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 CY2310ANZ can be used in conjunction with the CY2281 or similar clock synthesizer for a full Pentium II motherboard solution. The CY2310ANZ also includes a serial interface which can enable or disable each output clock. On power-up, all output clocks are enabled. A separate Output Enable pin facilitates testing on ATE.
