SDA
I/O
Serial Data Interface
This is the bidirectional data pin (SDA) for the I
2
C mode.
SDA is a digital open-drain bi-directional internally referenced to VDD_DIG.
SDA must have an external pull-up resistor (I
2
C bus pull-up) to same volt-
age as VDD_DIG.

OUT0b
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.
16
OUT0
O
17
VDDO0
P
Supply Voltage (1.8–3.3 V, or 1.5 V for CMOS only) for OUT0
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.

OUT1b
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.

OUT1
O
20
VDDO1
P
Supply Voltage (1.8–3.3 V, or 1.5 V for CMOS only) for OUT1 and OUT2
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.

OUT2b
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

INPUT4
I
Universal HW Input pin. This hardware input pin is user definable through
ClockBuilder Pro. Refer to Section
3.7 Universal Hardware Input Pins
for a
list of definitions that hardware input pins can be used for.
24
VDDO2
P
Supply Voltage (1.8–3.3 V, or 1.5 V for CMOS only) for OUT3, 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.
