1 CMS ECAL DAQ Fiber data block format Magnus Hansen 20020226

2 20020226Magnus Hansen, CERN-EP/CME Protocol Considerations l CMS ECAL FrontEnd is sending one Trigger Tower on one 800Mb optical link to the counting room l CIMT protocol is proposed s as opposed to 8/10 è 8/10 more “standard” s CIMT considered to be more robust s GOL used as serialiser s Agilent Technologies G-Link 1034 used as de-serialiser l Some link data format needed

3 20020226Magnus Hansen, CERN-EP/CME Features l CIMT protocol s Proprietary protocol è Agilent è IEEE standard... s Data word è 16 data bits è Flag bit s Control word è 14 data bits s Idle word è Fill frames l 8-10 protocol s Standard protocol s Data word è 8 data bits è 16 bits sent as two consecutive words s Idle word è Fill frames è Commas etc.

4 20020226Magnus Hansen, CERN-EP/CME CIMT Data link format word definition l Local BCID s Control word “01” è 12 bits l Local EVID s Control word “10” è 12 bits øGlobal triggers øLaser triggers øMonitoring triggers l Channel ID s Control word “00” è 3 bit channel (1-5) è 3 bit strip (1-5) è 7 bits tower (1-68) è parity? l Sample s Data word è 12 bit ADC data è 2 bit FPPA gain è 1 bit monitoring flag è 1 bit forced gain flag è Parity (flag bit) l Checksum s Control word “11” è Vertical XOR è Other l Idle word s Fill frame

5 20020226Magnus Hansen, CERN-EP/CME CIMT DAQ link data block format l CIMT protocol l One tower event s BCID s EVID s 1 tower sum s 25 channels è 1 channel header è 10 samples / channel s Checksum l N.o. clock cycles s 4 + (10 + 1) * 25 = 279 cp è 6.975 us

6 20020226Magnus Hansen, CERN-EP/CME 8-10 Data link format word definition l Idle word s Fill frame l Local BCID s Control word “01” è 12 bits BCID è 2 bits “01” è Forced gain flag l Local EVID s Control word “10” è 12 bits EVID øGlobal triggers øLaser triggers øMonitoring triggers è 2 bits “10” è Forced gain bit l Channel ID s Control word “00” è 3 bit channel (1-5) è 3 bit strip (1-5) è 7 bits tower (1-68) è parity? l Sample s Data word è 12 bit ADC data è 2 bit FPPA gain è 1 bit monitoring flag l Checksum s Control word “11” è Vertical XOR è Other

7 20020226Magnus Hansen, CERN-EP/CME DAQ link data block format l 8-10 protocol l One tower event s BCID s EVID s 1 tower sum s 25 channels è 1 channel header è 10 samples / channel s Checksum l N.o. clock cycles s 4 + (10 + 1) * 25 = 279 cp è 6.975 us l No Parity
