PAR/SER (Pin 35): Programming Mode Selection Pin.
Connect to ground to enable the serial programming
mode. CS, SCK, SDI and SDO become a serial interface
that controls 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(Pin36):ReferenceVoltageOutput.Bypasstoground
with a 1F ceramic capacitor, nominally 1.25V.
SENSE (Pin 38): 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.
OUT2B/OUT2B+, OUT2A,OUT2A+ (Pins 19/20, 21/22):
Serial Data Outputs for Channel 2. In 1-lane output mode,
only OUT2A/OUT2A+ are used.
FR/FR+ (Pin 23/Pin 24): Frame Start Output.
DCO/DCO+ (Pin 27/Pin 28): Data Clock Output.
OUT1B/OUT1B+, OUT1A/OUT1A+ (Pins 29/30, 31/32):
Serial Data Outputs for Channel 1. In 1-lane output mode,
only OUT1A/OUT1A+ are used.
