Abstract
| The TDCPix is a hybrid pixel detector readout ASIC designed for the NA62 GigaTracker detec- tor. The asynchronously operating pixel array consists of 1800 pixels, each 300x300 m m 2 . The requirements are a single-hit timing resolution better than 200 ps RMS and a read-out efficiency of 99% or better in the presence of a beam rate between 800 MHz and 1 GHz . The discrimina- tor time walk effect is compensated by time-over-threshold discriminators connected to an array of 360 dual TDC channels. The TDCpix processes up to 210 Mhits = s and provides the hit data without the need of a trigger in a continuous data stream via four 3.2 Gb = s serialisers. Under test since January 2014, the TDCPix chip is fully functional and shows excellent performance. |
