with a 1μF ceramic capacitor, nominally 1.25V.
SENSE (Pin 50): Reference Programming Pin. Connecting

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
All pins in this section 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.
