V
CC
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.

CLKSEL
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.
3 CLK0 Noninverting Differential Clock Input 0. Internal 75kΩ pulldown resistor.
4 CLK0 Inverting Differential Clock Input 0. Internal 75kΩ pullup and pulldown resistors.
