to use altlvds,how I can use LVDS bit clock and LVDS frame clock of ADC at the same t

You can only use one clock to clock in the data. My original thought was to use the bit clock to capture the data and the frame signal, and then use the frame signal to word-align the incoming data. The problem is that the frame clock is shifted from the data, so if the capture clock is lined up at the best possible time to capture the data, it is the worst possible time to capture the frame.

Could you ignore the bit clock and just use the frame clock to capture the data? I think the parallel data will come out word aligned. (Does altlvds support x7 deserialization? I don't remember, but that may be an issue)
