ECS in RICH Upgrade Rui Gao, University of Oxford LHCb Electronics Upgrade Meeting 14th April, 2012, CERN
LHCb Electronics Upgrade, CERN, 12/04/2012 RICH Level 0 Diagram Level 0 Board GBT GBT GBT GBT • Level0: • 1 fixed (Master) GBT with SCA • 4xMaPMT(64-ch each) • 8FE IC (CLARO) per MaPMT • up to 4 Add-on GBT • Configurable DC-DC convertors • 180 SCAs in RICH1 • 240 SCAs in RICH2 FPGA GBT CLARO SCA CLARO CLARO CLARO
LHCb Electronics Upgrade, CERN, 12/04/2012 ECS in RICH Upgrade • Completely redesign of Front End electronics, ECS using GBT-SCA, replacing SPECS. Functions of ECS: • Calibration & settings • MaPMT gain correction settings • Shaper threshold settings • Configuring add-on GBT modules • Monitoring • Temperature • Voltage and current • Testing • FE on-chip testing • Add-on GBT modules
LHCb Electronics Upgrade, CERN, 12/04/2012 FE requirement • Future FE IC (CLARO as an example) • 8-bit register for gain and threshold settings per channel, 8 channels per chip • 16-bit global settings • Total: 80 bits per IC. • 32 FE ICs per Level 0/SCA – 2560 bits • 9 addresses per IC on a I2C bus – 4 IC / 36 address per Level 0/SCA. • Use 4 I2C masters in a SCA for FE ICs. • Add-on GBT monitoring and configure – number of bits to be followed up.
LHCb Electronics Upgrade, CERN, 12/04/2012 SCA Resources • 32 I2C Masters • 4 - One per MaPMT for gain/threshold settings (via FPGA) • 4 - FE chip testing • 4 - Add-on GBT configuration and monitoring • JTAG • Reconfigure FPGA? • ADC 12bit 32-multiplexed input • 1 or more channel - temperature monitoring • 1 channel per power module - Current sensing • 1 channel per power module - Voltage monitoring • Parallel I/O • FE IC testing
