6. Prototype Link Requirements
Transfer data at line speed
Survive BER (~ 1 error/sec) with negligible loss in throughput and error rate.
Provide low-bandwidth return channel for link monitoring, or other purposes
Easy to implement in commodity FPGAs
Simple enough to describe in 1 slide! (maybe )

9. Some more protocol details...
LSC sends init packet with Link ID, waits for ACK
LSC breaks data into 4k packets
Send up to ~ 4 packets, wait for ACK
If ACK seen, delete packet from queue
If no ACK in 215 bit periods (65 us), re-send last non-acknowledged packet
LDC receives packets, checks CRC, ACKs correctly- formed packets.
No ACK sent if packet has error
No ACK send if Rx buffer is full

Status and Plans
Implement receiver for 5Gb/s link in MOL (underway!)
Test and discuss/modify protocol
Implement DAQ for HCAL
Receive data from AMC cards (see backup slides)
Transmit to MOL
(can receive in AMC13 and readout over Ethernet in interim)
Establish specifications for 10Gb/s link and start development of next gen AMC13
