Signal Description
74 Datasheet
NOTE:
1. It is highly recommended to prioritize 27/14.318/24/48 MHz clocks on CLKOUTFLEX1 and
CLKOUTFLEX3 outputs. Intel does not recommend configuring the 27/14.318/24/48 MHz
clocks on CLKOUTFLEX0 and CLKOUTFLEX2 if more than 2x 33 MHz clocks in addition to
the Feedback clock are used on the CLKOUT_PCI outputs.
2.20 LVDS Signals
All signals are Mobile Only, except as signals noted otherwise that are available in the
desktop package.
