pin FuncTions
SENSE(Pin50):ReferenceProgrammingPin.Connecting
SENSEtoVDDselectstheinternalreferenceanda±1Vinput
range. Connecting SENSE to ground selects the internal
reference and a ±0.5V input range. An external reference
between 0.625V and 1.3V applied to SENSE selects an
input range of ±0.8 VSENSE.
Exposed Pad (Pin 53): Ground. The Exposed Pad must
be soldered to the PCB ground.
LVDS Outputs
All pins in this section are differential LVDS outputs.
The output current level is programmable. There is an
optional internal 100 termination resistor between
the pins of each LVDS output pair.
OUT4B/OUT4B+, OUT4A/OUT4A+ (Pins 23/24, 25/26):
Serial data outputs for Channel 4. In 1-lane output mode
only OUT4A/OUT4A+ are used.
OUT3B/OUT3B+, OUT3A/OUT3A+ (Pins 27/28, 29/30):
Serial data outputs for Channel 3. In 1-lane output mode
only OUT3A/OUT3A+ are used.
FR/FR+ (Pins 31/32): Frame Start Outputs.
DCO/DCO+ (Pins 35/36): Data Clock Outputs.
OUT2B/OUT2B+, OUT2A/OUT2A+ (Pins 37/38, 39/40):
Serial data outputs for Channel 2. In 1-lane output mode
only OUT2A/OUT2A+ are used.
OUT1B/OUT1B+, OUT1A/OUT1A+ (Pins 41/42, 43/44):
Serial data outputs for Channel 1. In 1-lane output mode
only OUT1A/OUT1A+ are used.
