www.fairchildsemi.com TDC1049 High-Speed A/D Converter 9-Bit, 30 Msps Features 30 Msps conversion rate, 15 MHz analog bandwidth 9-Bit resolution and linearity Sample-and-hold circuit not required Differential phase 0.5 degrees www.DataSheet4U.com Differential gain 1.0% Overflow flag Single -5.2V power supply Differential ECL outputs Available in a 64-pin DIP, 68-contact LCC and 68-pin ceramic pin grid array Description The TDC1049 is a flash (full-parallel) analog-to-digital converter capable of converting analog signals with fullpower frequency components up to 15 MHz into 9-bit words at rates up to 30 Msps (Megasamples Per Second). A sample-and-hold circuit is not required. All digital inputs and outputs are differential ECL. The TDC1049 consists of 512 latching comparators, encoding logic and an output register. A differential convert signal controls the conversion operation. The outputs can be connected to give either true or inverted binary or offset two’s complement fommats.
