T he AD9701 is a high speed, 8-bit digital-to-analog converter
with fully integrated composite video functions. High speed
ECL input registers provide synchronous operation of data and
control functions up to 250 MSPS.
T he AD9701 incorporates onboard control functions including
horizontal sync, blanking, reference white level and a 10%
bright signal for highlighting. T he setup level is also adjustable
from 0 IRE units to 20 IRE units through the control pin. An
internal voltage reference allows the AD9701 to operate as a
stand-alone video reconstruction DAC.
T he AD9701 is available as an industrial temperature range
device, –25
