video signals at resolutions up to
1280 x 1024 with 75 Hz refresh rate. Compatible video
formats include NTSC-601, PAL-601, SMPTE 293M,
SMPTE 296M and SMPTE 274M.
The ADC sampling clock can be derived from either an
external source or from incoming horizontal sync using the
internal PLL. Setup and control is via registers accessible
through an SMBus/I
C compatible serial port.

Input amplitude range is 500–1000mV with either DC or AC
coupling. AC coupled inputs can be clamped to program-
mable midpoint/bottom levels or to external reference levels
using either internal or externally generated clamp timing.
Common to the three channels are clamp pulses, a bandgap
reference voltage and clocks derived from the HSYNC PLL
or an external clock source. Digital data output levels are
2.5–3.3V CMOS compliant.
Power is derived from a single +3.3 Volt power supply. Package
is a low cost 100-lead MQFP. Performance specifications are
guaranteed over 0°C to 70°C.
