V
BB0
Reference Output Voltage. Connect to the inverting or noninverting clock input to provide a reference for
single-ended operation. When used, bypass V
BB0
to V
CC
with a 0.01μF ceramic capacitor. Otherwise
leave open. V
BB0
is internally connected to V
BB1.

Negative Supply Voltage
Inverting Output for MUX 1. Typically terminate with 50
resistor to V
CC
- 2V.
Noninverting Output for MUX 1. Typically terminate with 50
resistor to V
CC
- 2V.
Positive Supply Voltage. Bypass each 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.
