pin FuncTions
PAR/SER (Pin 47): Programming Mode Selection Pin.
Connect to ground to enable serial programming mode.
CS, SCK, SDI and SDO become a serial interface that con-
trols the A/D operating modes. Connect to VDD to enable
parallel programming mode where CS, SCK, SDI and SDO
become parallel logic inputs that control a reduced set of
the A/D operating modes. PAR/SER should be connected
directly to ground or the VDD of the part and not be driven
by a logic signal.
VREF(Pin48):ReferenceVoltageOutput.Bypasstoground
with a 1F ceramic capacitor, nominally 1.25V.
SENSE (Pin 50): Reference Programming Pin. Connect-
ing SENSE to VDD selects the internal reference and a
±1V input 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.
LVDS OUTPUTS
The following pins are differential LVDS outputs. The
output current level is programmable. There is an op-
tional internal 100 termination resistor between the
pins of each LVDS output pair.
OUT4B–/OUT4B+, OUT4A–/OUT4A+ (Pins 23/24,
Pins 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,
Pins 29/30): Serial Data Outputs for Channel 3. In
1-lane output mode, only OUT3A–/OUT3A+ are used.
FR–/FR+ (Pin 31/Pin 32): Frame Start Output.
DCO–/DCO+ (Pin 35/Pin 36): Data Clock Output.
OUT2B–/OUT2B+, OUT2A–/OUT2A+ (Pins 37/38,
Pins 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,
Pins 43/44): Serial Data Outputs for Channel 1. In
1-lane output mode, only OUT1A–/OUT1A+ are used.
