Description
The TDC1049 is a flash (full-parallel) analog-to-digital
converter capable of converting analog signals with full-
power 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, encod-
ing 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.
