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 V supply
Packages: 24-pin QSOP (Q) and 24-pin TSSOP (L)
Product Description
PI6C2310 is a low skew, low jitter, PLL clock buffer with divider or
multiplier designed for PCI-X application in servers and worksta-
tions. There are two selectable input ranges using HF# input: 10-40
MHz and 40-80 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.
