Abstract
The CBC3 is the latest version of the CMS Binary Chip ASIC for readout of the outer radial region of the upgraded CMS Tracker at HL-LHC. This 254-channel, 130nm CMOS ASIC is designed to be bump-bonded to a substrate to which sensors will be wire-bonded. It will instrument double-layer 2S-modules, consisting of two overlaid silicon microstrip sensors with aligned microstrips. On-chip logic identifies L1 trigger primitives from high transverse-momentum tracks by selecting correlated hits in the two sensors. Delivered in late 2016, the CBC3 has been under test for several months, including x-ray irradiations and SEU testing. Results and performance are reported.
