FUNCTION
Positive Supply Voltage. Bypass from V
CC
to V
EE
with 0.1µF and 0.01µF ceramic capacitors. Place the
capacitors as close to the device as possible with the smaller value capacitor closest to the device.
Clock Select Input (Single-Ended). Drive low to select the CLK0,
CLK0
input. Drive high to select the
CLK1,
CLK1
input. The CLKSEL threshold is V
BB
. If CLKSEL is not driven by a logic signal, use a 1kΩ
pulldown to V
EE
to select CLK0,
CLK0,
or a 1kΩ pullup to V
CC
to select CLK1,
CLK1.
Noninverting Differential Clock Input 0. Internal 75kΩ pulldown resistor.
Inverting Differential Clock Input 0. Internal 75kΩ pullup and pulldown resistors.
Reference Output Voltage. Connect to the inverting or noninverting clock input to provide a reference for
single-ended operation. When used, bypass with a 0.01µF ceramic capacitor to V
CC
; otherwise, leave open.
Noninverting Differential Clock Input 1. Internal 75kΩ pulldown resistor.
Inverting Differential Clock Input 1. Internal 75kΩ pullup and pulldown resistors.
