PI6CL10804 1.2V/1.5V, 200MHz, 1:4 Networking Clock Buffer Features Description • High-speed, low-noise, non-inverting 1:4 buffer The PI6CL10804 is a 1.2V or 1.5V high-speed, low-noise 1:4 non-inverting clock buffer. The key goal in designing the PI6CL10804 is to target networking applications that require low-skew, low-jitter, and high-frequency clock distribution. • Maximum Frequency up to 200 MHz • Low output skew < 100ps • Low propagation delay < 3.5ns Providing output-to-output skew as low as 100ps, the PI6CL10804 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 • 3.3V tolerent input • 1.2V or 1.5V supply voltage • Packages (Pb-free & Green available): -8-pin SOIC (W) Block Diagram Pin Configuration OE CLK0 CLK1 BUF_IN 1 8 OE CLK0 2 7 VDD CLK1 3 6 GND CLK2 4 5 CLK3 BUF_IN CLK2 CLK3 Pin Description Pin Name BUF_IN CLK [0:3] GND VDD OE 13-0130 1 Description Input Outputs Ground Power Output Enable PI6CL10804 Rev B 08/09/2013 PI6CL10804 1.2V/1.5V, 200MHz, 1:4 Networking Clock Buffer 1.5V Absolute Maximum Ratings (Above which the useful life may be impaired.
