26
OUT4b
O
Output Clock
These output clocks support a programmable signal swing and common
mode voltage. Desired output signal format is configurable using register
control. Termination recommendations are provided in
3.5.3 LVCMOS Output Terminations
should be left unconnected.

VDDO3
P
Supply Voltage (1.8–3.3 V, or 1.5 V for CMOS only) for OUT4 and OUT5
See the
Si5332 Family Reference Manual
for power supply filtering recom-
mendations.
Leave VDDOx pins of unused output drivers unconnected. An alternate
option is to connect the VDDOx pin to a power supply and disable the
output driver to minimize current consumption.

OUT5b
O
Output Clock
These output clocks support a programmable signal swing and common
mode voltage. Desired output signal format is configurable using register
control. Termination recommendations are provided in
3.5.3 LVCMOS Output Terminations
should be left unconnected.
