PI6C10807 1.8V/2.5V, 250MHz, 1:10 Networking Clock Buffer Features Description • High-speed, low-noise, non-inverting 1-10 buffer The PI6C10807 is a 1.8V, or 2.5V high-speed, low-noise 1-10 non-inverting clock buffer. The key goal in designing the PI6C10807 is to target networking applications that require lowskew, low-jitter, and high-frequency clock distribution. • Maximum Frequency up to 250 MHz • Low output skew < 60ps • Low duty cycle distortion < 200ps Providing output-to-output skew as low as 60ps, the PI6C10807 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. • Low propagation delay < 2.0ns • Multiple VDD, GND pins for noise reduction • 1.8V or 2.5V supply voltage • Packages (Pb-free & Green): ▫20-pin, TSSOP (L20) ▫20-pin, SSOP (H20) Block Diagram Pin Configuration BUF_IN 1 20 VDD GND 2 19 CLK9 CLK0 3 18 CLK8 VDD 4 17 GND CLK1 5 16 CLK7 GND 6 15 VDD CLK2 7 14 CLK6 VDD 8 13 GND CLK3 9 12 CLK5 GND 10 11 CLK4 Pin Description Pin Name BUF_IN CLK [0:9] GND VDD 09-0084 1 Description Input Outputs Ground Power PS8862L 05/01/09 PI6C10807 1.8V/2.5V, 250MHz, 1:10 Networking Clock Buffer 2.5V Absolute Maximum Ratings (Above which the useful life may be impaired.
