A point-to-point link for data, trigger, clock and control over copper or fibre

Upgrades of the LHC detectors target significantly higher event rates and higher bandwidth over point-to-point links. The Data, Trigger, Clock and Control (DTCC) is a new custom link protocol for data and control streams over different physical media, as copper or optical fibre. The DTCC link is imp...

Sumario:Upgrades of the LHC detectors target significantly higher event rates and higher bandwidth over point-to-point links. The Data, Trigger, Clock and Control (DTCC) is a new custom link protocol for data and control streams over different physical media, as copper or optical fibre. The DTCC link is implemented over 8b10b encoding. A version of the DTCC link over standard Category 6 cables is planned to be used with ALICE EMCal Calorimeters after its LS1 upgrade with a significant increase of the readout rate [1].
