PI6C10804 1.5V/1.8V/2.5V, 180MHz, 1:4 Networking Clock Buffer Features Description • High-speed, low-noise, non-inverting 1:4 buffer The PI6C10804 is a 1.5V to 2.5V high-speed, low-noise 1:4 non-inverting clock buffer. The key goal in designing the PI6C10804 is to target networking applications that require lowskew, low-jitter, and high-frequency clock distribution. • Maximum Frequency up to 180 MHz • Low output skew < 70ps (1.8V, 2.5V), <100ps (1.5V) • Low propagation delay < 3.0ns (1.8V, 2.5V), <3.5ns (1.5V) Providing output-to-output skew as low as 70ps, the PI6C10804 is an ideal clock distribution device for synchronous systems. Designing synchronous networking systems requires a tight level of skew from a large number of outputs. • Optimized duty cycle • 1.5V - 2.5V supply voltage • 3.3V Tolerant input clock • Packages (Pb-free & Green available): −8-pin SOIC (W) Block Diagram Pin Configuration OE CLK0 BUF_IN 1 8 OE CLK0 2 7 VDD CLK1 3 6 GND CLK2 4 5 CLK3 CLK1 BUF_IN CLK2 CLK3 Pin Description Pin Name BUF_IN CLK [0:3] GND VDD OE 09-0056 1 Description Input Outputs Ground Power Output Enable PS8822G 10/07/09 PI6C10804 1.5V/1.8V/2.5V, 180MHz, 1:4 Networking Clock Buffer 2.5V Absolute Maximum Ratings (Above which the useful life may be impaired.
