UpdatedSummary by A. Kluge - PHOS withreference to TPC and EMCal BLUE: informationadded or updated (24 CRUs if separate readoutadded FEE TOF electronics) RED: RO optionbasedon TPC type P2P, under development in Bergen, seefollowingpages To implementthe EMCal type P2P, necessaryengineeringresources must be found, under discussion.
KeepFECs • 112 FECs per module • 64 channels per FEC (32 Lowgain + 32 High gain) • Black event: 64 channels x 64 timebins x 10 bits: 41 kbit/event per FEC • Alternative: 32 timebins withshorter FEC shaping time => 20 kbit/event per FEC • Zero-suppression (10% occupancy): 4 kbit/event per FEC-> 200 Mbit/s @ 50 kHz (100 Mbit/s @ 50 kHz)-> scale up withhigheroccupancy in Pb-Pb • Upgrade architecture: P2P links (optical or electrical) to CRU Upgrade ofthe PHOS readoutelectronics
