Upstream Timing
1) FCLP signal rise/fall times are the rise/fall times of the LVDSM pads, and the high/low times are min 1 * T_A.
2) T_A depends on the clock source selected for baud rate generation in the ABRA block of the MSC.
3) FCLP signal high and low can be minimum 1 * T_MSC.
4) The PLL jitter is not included. It should be considered additionally, corresponding to the used baudrate. The duty cycle can
be adjusted if the ABRA block is used.
5) Positive deviation lenghtens the high time and shortens the low time of a clock period. Negative deviation does the
opposite.
6) From FCLP rising edge.
7) When using slow and asymmetrical edges, like in case of open drain upstream connection, the application must take care
that the bit is long enough (the baud rate is low enough) so that under worst case conditions the three sampling points in
the middle of the bit are not violated.
