PIN FUNCTIONS
V
with a 2.2µF ceramic capacitor. The reference output is
nominally 1.25V.
SENSE (Pin 50): Reference Programming Pin. Connecting
SENSE to V
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 • V
LVDS Outputs
The following pins are differential LVDS outputs. The
output current level is programmable. There is an optional
internal 100Ω termination resistor between the pins of
each LVDS output pair.
REF
(Pin 48): Reference Voltage Output. Bypass to ground
DD
selects the internal reference and a ±1V input
