Reserved.
This bit selects the active edge of the RCLKn pin.
0: Rising edge. (default)
1: Falling edge.
This bit determines the active level on the RDPn and RDNn pins.
0: Active high. (default)
1: Active low.
This bit selects the line code rule for the receive path.
0: B8ZS (in T1/J1 mode) / HDB3 (in E1 mode). (default)
1: AMI.
These bits determines the receive system interface.
01: Receive Dual Rail NRZ Format system interface. The data is output on RDPn and RDNn in NRZ format and a 1.544 MHz (in
T1/J1 mode) or 2.048 MHz (in E1 mode) recovered clock is output on RCLKn. (default)
10: Receive Dual Rail RZ Format system interface. The data is output on RDPn and RDNn in RZ format and a 1.544 MHz (in T1/
J1 mode) or 2.048 MHz (in E1 mode) recovered clock is output on RCLKn.
11: Receive Dual Rail Sliced system interface. The data is output on RDPn and RDNn in RZ format directly after passing through
the Slicer.
Reserved.
These bits select the Monitor Gain.
00: 0 dB. (default)
01: 20 dB.
10: 26 dB.
11: 32 dB.
