1 PIC Product Features Four synchronous outputs Selectable divider/multiplier Output Enable control Low phase error < 50 ps Allows clock input to have spread spectrum modulation for EMI reduction Low output skew < 200 ps Low cycle jitter < 200 ps Industrial temperature ( 40 C to 85 C) 3.3V supply Packages (Pb-free and Green available): -pin QSOP (Q) -pin SSOP (L) Product Description PIC0 is a low skew, low jitter, PLL clock buffer with divider or multiplier designed for PCI-X application in servers and workstations. here are two selectable input ranges using HF# input: 0-40 MHz and MHz. All outputs are synchronized to the input and to the other outputs. Each output can be independently turned off to reduce EMI and power consumption.
