TMC1203

www.fairchildsemi.com TMC1203 Triple Video A/D Converter 8-Bit, 50Msps Features 8-bit resolution 50 Msps conversion rate Low power: 100mW per channel @ 20 Msps Integral track/hold Independent clock inputs Integral and differential linearity error 0.5 LSB Differential phase 0.7 degree Differential gain 1.8% Single +5V power supply Three-state TTL/CMOS-compatible outputs Low cost Applications Video digitizing (composite and Y-C) VGA and CCD digitizing LCD projection panels Image scanners Personal computer video boards Multimedia systems Low cost, high speed data conversion Digital communications Description Incorporated into the TMC1203 are three analog-to-digital (A/D) converters, each with independent clocks and reference voltages. Analog signals are converted to Triple 8-bit digital words at sample rates up to 50 Msps (Megasamples per second) per channel. Integral Track/Hold circuits deliver excellent performance on signals with full-scale spectral components up to 12 MHz. Innovative two-step architecture conversion architecture and submicron CMOS technology reduce typical power dissipation to 100 mW per converter. Power is derived from a single +5 Volt power supply. Outputs are three-state outputs and TTL/CMOS-compatible. TMC1203 package is a 80-lead Metric Quad Flat Pack (MQFP). Performance specifications are guaranteed from 0°C to 70°C.
