FMS9874A

Notes:
1. Functional operation under any of these conditions is NOT implied. Performance and reliability are guaranteed only if Operating Conditions are not exceeded.
2. Applied voltage must be current limited to specified range.
3. Forcing voltage must be limited to specified range.
4. Current is specified as conventional current flowing into the device.
5. EIAJ test method.

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 of FMS9874A 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 compatibleserial port.



Input amplitude range of FMS9874A is 5001000mV with either DC or AC coupling. Lower reference of AC coupled inputs is established 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 of FMS9874A derived from a PLL locked to HSIN or an external source. Digital data levels are 2.53.3V CMOS compliant.

Power of FMS9874A can be derived from a single +3.3 Volt power supply.

Package of FMS9874A is a 100-lead MQFP. Performance specifications are guaranteed over 0 to 70 range.
