LOW SKEW, 1-TO-4, CRYSTAL-TO-LVCMOS/LVTTL FANOUT BUFFER
RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS
INPUTS:
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 1kΩ resistor can be tied
from XTAL_IN to ground.
OUTPUTS:
LVCMOS OUTPUTS
All unused LVCMOS output can be left floating. There should be
no trace attached.
CLK INPUT
For applications not requiring the use of the clock input, it can be
left floating. Though not required, but for additional protection, a
1kΩ resistor can be tied from the CLK input to ground.
SELECT PINS
All select pins have internal pull-ups and pull-downs; additional
resistance is not required but can be added for additional
protection. A 1kΩ resistor can be used.
