The CY29653 is a low-voltage high-performance 125-MHz PLL-based zero delay buffer designed for high-speed clock distribution applications. The CY29653 features an LVPECL reference clock input and provides eight outputs plus one feedback output. VCO output divides by four or eight per VCO_SEL setting (see the Function Table). Each LVCMOS-compatible output can drive 50 series- or parallel-terminated transmission lines. For series-terminated transmission lines, each output can drive one or two traces giving the device an effective fanout of 1:16.
