Applications Information

Recommendations for Unused Input and Output Pins

Inputs:

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



resistor can be tied from the REF_CLK to ground.

Crystal Inputs

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.

LVCMOS Control Pins

All control pins have internal pullups or pulldowns; additional

resistance is not required but can be added for additional protection.

A 1k

 resistor can be used.

Outputs:

LVDS Outputs

All unused LVDS output pairs can be either left floating or terminated

with 100

 across. If they are left floating, there should be no trace

attached.
