PI6C2405A-1HLIE

PI6C2405A Zero-Delay Clock Buffer Features Description • Maximum rated frequency: 133 MHz • Low cycle-to-cycle jitter • Input to output delay, less than 300ps • Internal feedback allows outputs to be synchronized to the clock input • 5V tolerant input* • Spread spectrum clock ready • Operates at 3.3V VDD • Packaging (Pb-free & Green available): -8-pin, 150-mil SOIC (W) -8-pin, 173-mil TSSOP (L) The PI6C2405A is a PLL based, zero-delay buffer, with the ability to distribute five outputs of up to 133MHz at 3.3V. All the outputs are distributed from a single clock input CLKIN and output OUT0 performs zero delay by connecting a feedback to PLL. An internal feedback on OUT0 is used to synchronize the outputs to the input; the relationship between loading of this signal and the outputs determines the input-output delay. PI6C2405A is able to track spread spectrum clocking for EMI reduction. PI6C2405A is characterized for both commercial and industrial operation. PI6C2405A-1H is a high-drive version of PI6C2405A-1 * CLKIN must reference the same voltage thresholds for the PLL to deliver zero delay skewing Block Diagram Pin Configuration PLL CLKIN OUT0 CLKIN 1 8 OUT0 OUT1 OUT2 2 7 OUT4 OUT1 3 6 VDD GND 4 5 OUT3 OUT2 OUT3 PI6C2405A(–1, –1H) OUT4 Pin Description Pin Signal Description 1 CLKIN Input clock reference frequency (weak pull-down) 2, 3, 5, 7 OUT[1-4] Clock Outputs 4 GND Ground 6 VDD 3.3V Supply 8 OUT0 Clockoutput, internal PLL feedback (weak pull-down) 11-0001 1 PS8592I 04/29/10 PI6C2405A Zero Delay Clock Buffer Zero Delay and Skew Control CLKIN Input to OUTx Delay vs. Difference in Loading between OUT0 pin and OUTx pins CLKIN - Input to OUTx Delay (ps) 800 600 400 200 0 -200 -25 -20 -15 -10 0 -5 5 10 15 -400 20 25 PI6C2405A-1H -600 -800 PI6C2405A-1 -900 -1000 Output Load Difference: OUT0 Load - OUTx Load (pF) The relationship between loading of the OUT0 signal and other outputs determines the input-output delay. Zero delay is achieved when all outputs, including feedback, are loaded equally.
