Function
Full-Scale Adjust Pin. AVDD sets FS = 0.768 V p-p differential;
GND sets FS = 1.536 V p-p differential.
Do Not Connect.
Analog Ground. AGND and DRGND should be tied together to a common
ground plane.
3.3 V Analog Supply.
Data Format Select. GND = binary; AVDD = twos complement.
Set Pin for LVDS Output Current. Place a 3.74 k⦠resistor terminated to
ground.
Reference Mode Select Pin. Float for internal reference operation.
1.235 V Reference Input/Output. Function depends on SENSE.
Analog Input. True.
Analog Input. Complement.
Clock Input. True (LVPECL levels).
Clock Input. Complement (LVPECL levels).
