The AD9483 is a triple 8-bit monolithic analog-to-digital
converter optimized for digitizing RGB graphics signals from
personal computers and workstations. Its 140 MSPS encode
rate capability and full-power analog bandwidth of 330 MHz
supports display resolutions of up to 1280 × 1024 at 75 Hz with
sufficient input bandwidth to accurately acquire and digitize
each pixel.
To minimize system cost and power dissipation, the AD9483
includes an internal 2.5 V reference and track-and-hold circuit.
The user provides only a 5 V power supply and an encode clock.
No external reference or driver components are required for
many applications. The digital outputs are three-state CMOS
outputs. Separate output power supply pins support interfacing
with 3.3 V or 5 V logic.
The AD9483’s encode input interfaces directly to TTL, CMOS,
or positive ECL logic and will operate with single-ended or
differential inputs. The user may select dual channel or single
channel digital outputs. The Dual Channel (demultiplexed)
