Abstract :
A 32 channel 12 bit Time to Digital Converter (TDC) has been designed to fit in a single unit VME 6U. 32 Time to Amplitude Converter (TAC) sections and a multiplexer circuit are followed by a fast 12 bit ADC. The total handling and conversion time for all the channels is less than 10 μs. The differential nonlinearity is kept below 2%. The Common Start/Stop Mode, the Full Scale Range, the individual low and high threshold values and the self-test-mode are software selectable. The module has Zero Suppression and Chained Block Transfer protocol capabilities
