PIN NAME FUNCTION
29 SLVS/LVDS
Differential Output Signal Format Select Input. Drive SLVS/LVDS high to select SLVS outputs. Drive
SLVS/LVDS low to select LVDS outputs.
30 PLL0 PLL Control Input 0. PLL0 is reserved for factory testing only and must always be connected to GND.
31 PLL1 PLL Control Input 1. PLL1 is reserved for factory testing only and must always be connected to GND.
32 PLL2 PLL Control Input 2. See Table 1 for details.
33 PLL3 PLL Control Input 3. See Table 1 for details.

OV DD
Output-Driver Power Input. Connect OV DD to a 1.7V to 1.9V power supply. Bypass each OV DD to
GND with a 0.1µF capacitor as close to the device as possible. Bypass the OV DD power plane to the
GND ground plane with a bulk ≥ 2.2µF capacitor as close to the device as possible. Connect all OV DD
pins to the same potential.
35 OUT3N Channel 3 Negative LVDS/SLVS Output
36 OUT3P Channel 3 Positive LVDS/SLVS Output
38 OUT2N Channel 2 Negative LVDS/SLVS Output
39 OUT2P Channel 2 Positive LVDS/SLVS Output
41 FRAMEN
Negative Frame Alignment LVDS/SLVS Output. A rising edge on the differential FRAME output aligns
to a valid D0 in the output data stream.
42 FRAMEP
Positive Frame Alignment LVDS/SLVS Output. A rising edge on the differential FRAME output aligns to
a valid D0 in the output data stream.
44 CLKOUTN Negative LVDS/SLVS Serial Clock Output
45 CLKOUTP Positive LVDS/SLVS Serial Clock Output
47 OUT1N Channel 1 Negative LVDS/SLVS Output
48 OUT1P Channel 1 Positive LVDS/SLVS Output
50 OUT0N Channel 0 Negative LVDS/SLVS Output
51 OUT0P Channel 0 Positive LVDS/SLVS Output
53 PD0
Channel 0 Power-Down Input. Drive PD0 high to power-down channel 0. Drive PD0 low for normal
operation.
54 PD1
Channel 1 Power-Down Input. Drive PD1 high to power-down channel 1. Drive PD1 low for normal
operation.
55 PD2
Channel 2 Power-Down Input. Drive PD2 high to power-down channel 2. Drive PD2 low for normal
operation.
56 PD3
Channel 3 Power-Down Input. Drive PD3 high to power-down channel 3. Drive PD3 low for normal
operation.
57 PDALL
Global Power-Down Input. Drive PDALL high to power-down all channels and reference. Drive PDALL
low for normal operation.
63 T/B
Output Format Select Input. Drive T/B high to select binary output format. Drive T/B low to select two’s
complement output format.
