Arria V Transceiver Clocking

Hi,

I have sent a similar question to Altera Support team and received an answer from the CMU support group.

" transceivers consumes one additional transceiver as CMU."

1) a x8 bonded transceiver attempts to put the CMU in the middle transceivers ( total 9 transceivers)

2) a x4 bonded transceiver attempts to put the CMU in the beginning transceivers. ( total of 5 transceivers)

3) a single transceiver uses one additional transceiver as CMU. (total of 2 transceivers)

for system planning purposes,

1) single transceiver implementation use 200% as many transceivers as expected

2) quad transceiver implementation use 125% as many transceivers as expected

3) Octal transceiver implementation use 112% as many transceivers as expected

4) the pin assignments of the DK-START-5agxb3n preclude using all of the available serdes as transceivers.

An excellent example of QUAD transceiver implementation is the PCI-e x4 megawizzard.

An excellent example of OCTAL transceiver implementation is the PCI-e x8 megawizzard.
