PI49FCT3807 3.3V Fast CMOS Clock Driver Features Description • • • • • • • Pericom Semiconductor’s PI49FCT3807 is a 3.3V 1-to-10 clock driver. This low skew clock driver features one input and ten outputs fanout. The large fanout from a single input line reduces loading on input clock. TTL level ouputs reduce noise levels on the part. Typical applications are clock and signal distribution. 3.3V version of PI49FCT807 Ultra low skew: 0.35ns Low Input Capacitance Minimum duty cycle distortion 1:10 fanout High speed: 3.5ns propagation TTL input and CMOS output compatible – VOH = 3.3V (typical) – VOH = 0.3V (typical) • Industrial operation at –40°C to 85°C • Packaging (Pb-free & Green available): – 20-pin 300-mil wide SOIC (S) – 20-pin 150-mil wide QSOP (Q) – 20-pin 209mil wide SSOP (H) Pin Configuration Block Diagram B0 B1 B2 B3 B4 A A 1 20 VCC GND 2 19 B9 B0 3 18 B8 VCC 4 17 GND B1 5 16 B7 GND 6 15 VCC B2 7 14 B6 VCC 8 13 GND B3 9 12 B5 10 11 B4 GND B5 B6 Pin Description B7 B8 B9 1 Pin Name Description A Input B0 - B9 Outputs GND Ground VCC Power PS7010D 09/08/04 PI49FCT3807 3.3V Fast CMOS Clock Driver Maximum Ratings (Above which the useful life may be impaired.
