Description
TEMPOROC3 is a 64-channel SiPM read-out chip designed in TSMC130 technology. The ASIC aims at measuring the energy with 10-bit ADC, time-of-arrival (TOA) and time-over-threshold (TOT) with 40 ps bin TDC. The analog front-end offers a dynamic range up to 500 pC. The dual discriminator allows either to measure two TOA at different thresholds and at either rising or falling edge. Measurements in coincidence between 2 ASICs have shown TDC time resolution as low as 25 ps RMS (CTR). The dual-gain charge measurement integrates the input signal over a tunable range from 20 to 300 ns. The 64 channels are divided in 4 clusters, each outputting data at 320 Mbps. The clusters can be easily synchronized to stream all channel data whenever a channel from the matrix has triggered. The number of triggered channels (per cluster) required to launch the data serialization is programmable as well as the window duration for accepting new triggers. At 450 kEvents/s (with 1 TDC + 1 ADC per channel), the power consumption is about 8 mW per channel. TEMPOROC3 is a very versatile read-out ASIC with numerous configuration parameters that can find applications in for example Compton camera, LIDAR or also ToF-PET.
