PI49FCT20802/PI49FCT20803 1:5/1:7 2.5V Clock Buffer for Networking Applications Features Description ÎÎHigh Frequency >150 MHz The PI49FCT2080x is 2.5V, high-speed, low noise, non-inverting clock buffer. It is designed to target networking applications that require low-skew, low-jitter, and high-frequency clock distribution. It provides output-to-output skew as low as 150ps, and is an ideal clock distribution device for synchronous systems. PI49FCT2080x is a clock buffer from a single input that produces five outputs on PI49FCT20802 and seven outputs on PI49FCT20803. PI49FCT2080x is characterized for operation from –40°C to 85°C. ÎÎHigh-speed, low-noise, non-inverting clock buffer àà PI49FCT20802 is a 1:5 buffer àà PI49FCT20803 is a 1:7 buffer ÎÎLow skew < 150ps ÎÎLow duty cycle distortion < 300ps ÎÎLow propagation delay < 3.5ns ÎÎMultiple VDD, GND pins for noise reduction ÎÎ2.5V supply voltage and 3V tolerant input ÎÎPackaging (Pb-free & Green): àà 16-pin TSSOP (L) àà 16-pin QSOP (Q) - PI49FCT20802 only Pin Configuration (PI49FCT20802) BUF_IN 1 16 VDD GND 2 15 CLK4 CLK0 3 14 CLK3 VDD 4 13 GND CLK1 5 12 CLK2 GND 6 11 VDD NC 7 10 NC VDD 8 9 Block Diagram (PI49FCT20802) CLK0 CLK1 BUF_IN CLK2 CLK3 CLK4 GND Pin Configuration (PI49FCT20803) 1 16 VDD GND 2 15 CLK6 CLK0 3 14 CLK5 VDD 4 13 GND CLK1 5 12 CLK4 GND 6 11 VDD CLK2 7 10 CLK3 VDD 8 9 GND 11-0004 CLK0 CLK1 BUF_IN CLK2 CLK3 ...
