LCDC[10:0]:

The LCDC[10:0] bits represent the number of consecutive cell periods the receive cell processor must be out of cell delineation before loss of cell delineation (LCD) is declared. Likewise, LCD is not de-asserted until receive cell processor is in cell delineation for the number of cell periods specified by LCDC[10:0].

The default value of LCD[10:0] is 360, which translates to an average cell period of 2.83 µs and a default LCD integration period of 1.02 ms.
