Honored ContributorHow does altlvds make bit alignment?
Hi, I'm currently using Cyclone III and trying to deserialize an LVDS data. It has 5 channel and 7bit data. 75MHz clock, deserialize factor is 7. I would like to ask a question. ...

Honored ContributorYou need to use the altlvds_rx IP core with an external frame clock with a frequency determined by the data bit-rate and LVDS deserialization factor. The bits are then packed into parallel words with respect to the frame clock.
For an example, see this document, p71: http://www.ovro.caltech.edu/~dwh/carma_board/digitizer_tests.pdf (http://www.ovro.caltech.edu/%7edwh/carma_board/digitizer_tests.pdf) Cheers, Dave
