ICS8761I

LOW VOLTAGE, LOW SKEW,

PCI / PCI-X CLOCK GENERATOR

INPUTS:

CRYSTAL INPUT:

For applications not requiring the use of the crystal oscillator

input, both XTAL_IN and XTAL_OUT can be left floating.

Though not required, but for additional protection, a 1k

resistor can be tied from XTAL_IN to ground.

REF_CLK INPUT:

For applications not requiring the use of the reference clock,

it can be left floating. Though not required, but for additional

protection, a 1k

Ω resistor can be tied from the REF_CLK to

ground.

LVCMOS CONTROL PINS:

All control pins have internal pull-ups or pull-downs; additional

resistance is not required but can be added for additional

protection. A 1k

Ω resistor can be used.

RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS

OUTPUTS:

LVCMOS OUTPUT:

All unused LVCMOS output can be left floating. We

recommend that there is no trace attached.
