Description
As a fully integrated analog interface, the FMS9874A can
directly digitize RGB graphics with resolutions up to
1024 x 768/85Hz and 1280 x 1024/75Hz; or using alternate
pixel sampling, 1600 x 1200/85Hz.
The ADC sampling clock can be derived from either an
external source or incoming horizontal sync signal using the
internal, PLL. Output data is 24-bit RGB. Setup and control is
via registers, accessible through an SMBus/I2C compatible
serial port.
Input amplitude range is 500–1000mV with either DC or AC
coupling. Lower reference of AC coupled inputs is estab-
lished by input clamps that are either internally generated or
externally provided.
Common to the three channels are clamp pulses, a bandgap
reference voltage and clocks derived from a PLL locked to
HSIN or an external source. Digital data levels are 2.5–3.3V
CMOS compliant.
Power can be derived from a single +3.3 Volt power supply.
Package is a 100-lead MQFP. Performance specications are
guaranteed over 0°C to 70°C range.
