Multi-Hit Time to Digital Conversion

 

In 1991, the MTD-132 circuit was, by far, the most complex, sophisticated and complete Time to Digital Conversion (TDC) system ever created - and perhaps in ways it remains so to this day. Operating with 0.5 ns resolution, each chip contained 8 channels, each of which could record 16 time measurements in rapid succession with essentially zero dead-time. A patented stale-data detection and elimination circuit managed the accumulation of data, ensuring that unwanted “stale” data was removed from its memory. The MTD-132 won an IR-100 award for innovation.
