Functional Description

The CY2304 is a 3.3 V zero delay buffer designed to distribute high-speed clocks in PC, workstation, datacom, telecom, and other high performance applications.

The part has an on-chip phase-locked loop (PLL) that locks to an input clock presented on the REF pin. The PLL feedback is required to be driven into the FBK pin, and can be obtained from one of the outputs. The input-to-output skew is guaranteed to be less than 250 ps, and output-to-output skew is guaranteed to be less than 200 ps.
