AIN1+ (Pin 1): Channel 1 Positive Differential Analog
Input.
AIN1– (Pin 2): Channel 1 Negative Differential Analog
Input.
VCM12 (Pin 3): Common Mode Bias Output, Nominally
Equal to VDD/2. VCM should be used to bias the common
mode of the analog inputs of channels 1 and 2. Bypass
to ground with a 0.1F ceramic capacitor.
AIN2+ (Pin 4): Channel 2 Positive Differential Analog
Input.
AIN2– (Pin 5): Channel 2 Negative Differential Analog
Input.
REFH (Pins 6, 7): ADC High Reference. Bypass to Pin 8
and Pin 9 with a 2.2F ceramic capacitor, and to ground
with a 0.1F ceramic capacitor.
REFL (Pins 8, 9): ADC Low Reference. Bypass to Pin 6
and Pin 7 with a 2.2F ceramic capacitor, and to ground
with a 0.1F ceramic capacitor.
AIN3+ (Pin 10): Channel 3 Positive Differential Analog
Input.
AIN3– (Pin 11): Channel 3 Negative Differential Analog
Input.
VCM34 (Pin 12): Common Mode Bias Output, Nominally
Equal to VDD/2. VCM should be used to bias the common
mode of the analog inputs of channels 3 and 4. Bypass
to ground with a 0.1F ceramic capacitor.
AIN4+ (Pin 13): Channel 4 Positive Differential Analog
Input.
AIN4– (Pin 14): Channel 4 Negative Differential Analog
Input.
VDD (Pins 15, 16, 51, 52): Analog Power Supply, 1.7V
to 1.9V. Bypass to ground with 0.1F ceramic capacitors.
Adjacent pins can share a bypass capacitor.
ENC+ (Pin 17): Encode Input. Conversion starts on the
rising edge.
ENC(Pin 18): Encode Complement Input. Conversion
starts on the falling edge.
CS(Pin19):Inserialprogrammingmode(PAR/SER=0V),
CS is the serial interface chip select input. When CS is low,
SCK is enabled for shifting data on SDI into the mode
controlregisters.Inparallelprogrammingmode(PAR/SER
= VDD), CS selects two-lane or one-lane output mode. CS
can be driven with 1.8V to 3.3V logic.
SCK (Pin 20): In serial programming mode (PAR/SER
= 0V), SCK is the serial interface clock input. In parallel
programming mode (PAR/SER = VDD),SCKselects3.5mA
or 1.75mA LVDS output currents. SCK can be driven with
1.8V to 3.3V logic.
SDI (Pin 21): In serial programming mode (PAR/SER =
0V), SDI is the serial interface data input. Data on SDI
is clocked into the mode control registers on the rising
edge of SCK. In parallel programming mode (PAR/SER =
VDD), SDI can be used to power down the part. SDI can
be driven with 1.8V to 3.3V logic.
GND (Pins 22, 45, 49, Exposed Pad Pin 53): ADC Power
Ground. The exposed pad must be soldered to the PCB
ground.
OGND (Pin 33): Output Driver Ground. Must be shorted
to the ground plane by a very low inductance path. Use
multiple vias close to the pin.
OVDD(Pin34):OutputDriverSupply,1.7Vto1.9V.Bypass
to ground with a 0.1F ceramic capacitor.
SDO (Pin 46): In serial programming mode (PAR/SER
= 0V), SDO is the optional serial interface data output.
Data on SDO is read back from the mode control reg-
isters and can be latched on the falling edge of SCK.
SDO is an open-drain N-channel MOSFET output that
requires an external 2k pull-up resistor of 1.8V to
3.3V. If readback from the mode control registers is
not needed, the pull-up resistor is not necessary and
SDO can be left unconnected. In parallel programming
mode (PAR/SER = VDD), SDO is an input that enables
internal 100 termination resistors on the digital
outputs. When used as an input, SDO can be driven
with 1.8V to 3.3V logic through a 1k series resistor.
