TALOS[1:0]
These bits select the amplitude threshold. When the amplitude of the data is less than the threshold for a certain period, TLOS is
declared. The period is determined by the TDLOS bits (b1~0, LOS,...). When the amplitude of a pulse is above the threshold,
TLOS is cleared.
For Differential line interface:
00: 1.2 Vp.
01: 0.9 Vp. (default)
10: 0.6 Vp.
11: 0.4 Vp.
For Single Ended line interface:
00: 0.61 Vp.
01: 0.48 Vp. (default)
10: 0.32 Vp.
11: 0.24 Vp.
1 - 0
TDLOS[1:0]
These bits select the period. When the amplitude of the data is less than a certain voltage for the period, TLOS is declared. The
voltage is determined by the TALOS bits (b3~2, LOS,...).
00: 16-pulse.
01: 32-pulse. (default)
1X: 64-pulse.
