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 1k
pulldown to V
EE
to select CLK0,
CLK0
, or a 1k
pullup to V
CC
to select CLK1,
CLK1
.
