Abstract

A 12-channel analog optical-receiver module has been developed for the compact muon solenoid (CMS) experiment to be installed at the European Organization for Nuclear Research (CERN) large hadron collider (LHC). It is based on a modified commercial 12-channel module, where the digital amplifier application-specified integrated circuit (ASIC) has been replaced by a custom-designed analog variant. The module features an 8-bit dynamic range with 1% integral-linearity deviation in a 100-MHz bandwidth. A user-configurable input capacitor-matching network allows for the control of the overshoot of the received pulse-amplitude-modulated signal. The ASIC-receiver-circuit implementation as well as the module design and manufacture are reviewed. Results of the successful functional performance evaluation of the module are shown.
