LOW VOLTAGE, LOW SKEW,
PCI / PCI-X CLOCK GENERATOR
8761 DATA SHEET
10 REVISION E 2/18/15
INPUTS:
CRYSTAL INPUT:
For applications not requiring the use of the crystal oscillator
input, both XTAL_IN and XTAL_OUT can be left fl oating. Though
not required, but for additional protection, a 1kΩ resistor can be
tied from XTAL_IN to ground.
REF_CLK I
NPUT:
For applications not requiring the use of the reference clock,
it can be left fl oating. Though not required, but for additional
protection, a 1kΩ resistor can be tied from the REF_CLK to
ground.
LVCMOS C
ONTROL PINS:
All control pins have internal pull-ups or pull-downs; additional
resistance is not required but can be added for additional
protection. A 1kΩ resistor can be used.
RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS
OUTPUTS:
LVCMOS OUTPUT:
All unused LVCMOS output can be left fl oating. We recommend
that there is no trace attached.
