LVDS Output Drivers
The AD9522 output drivers can be configured as either an
LVDS differential output or as a pair of CMOS single-ended
outputs. The LVDS outputs allow for selectable output current
from ~1.75 mA to ~7 mA.
The LVDS output polarity can be set as noninverting or
inverting, which allows for the adjustment of the relative
polarity of outputs within an application without requiring a
board layout change. Each LVDS output can be individually
powered down to save power.
