PI49FCT807T Fast CMOS Clock Driver Features Description Pericom Semiconductor’s PI49FCT807T clock driver feature one input and ten outputs. The large fanout from a single input line reduces loading on input clock. TTL level outputs reduce noise levels on the part. Typical applications are clock and signal distribution. Guaranteed low skew: 0.25ns Low input capacitance Minimum duty cycle distortion 1:10 fanout High speed: 3.5ns propagation delay TTL input and CMOS output compatible – VOH = 3.3V (typ.) – VOL = 0.3V (typ.)
