Product Description
PCS3P622S04J is a versatile, 3.3V Zero-delay buffer
designed to distribute low frequency Timing-Safe™ clocks
Block Diagram
with Peak EMI Reduction. PCS3P622S04J accepts one
reference input and drives out four low-skew clocks.
PCS3P622S04J has an on-chip PLL that locks to an input
clock on the XIN/CLKIN pin. The PLL feedback is on-chip
and is obtained from the CLKOUT pad, internal to the
device. PCS3P622S04J has a crystal oscillator interface.
An inexpensive crystal will provide the clock source for
distribution. It is available in 8 pin TSSOP.
All outputs have less than 200pS of Cycle-to-cycle jitter.
The input and output propagation delay is guaranteed to be
less than 350pS, and the output-to-output skew is
guaranteed to be less than 250pS.
