T1/J1 Receive Configuration 1 (029H, 129H, 229H, 329H, 429H, 529H, 629H, 729H)
EQ_ON:
LOS[4:0]:
pulse intervals. In long haul applications, these bits select the LOS declare threshold (Q). These bits are invalid in short haul applications.
Programming Information
IDT82P2288
Bit Name
= 0: The Equalizer is off in short haul applications.
= 1: The Equalizer is on in long haul applications.
A LOS is detected when the incoming signals has “no transitions”, i.e., when the signal level is less than Q dB below nominal for N consecutive
Default
