put on the RMFn pin.
000: PRBS/ARB indication when the PRBS/ARB detection is switched to the receive path. Or reserved when the PRBS/ARB
detection is switched to the transmit path. (default)
001: LAIS indication.
010: XOR data of positive and negative sliced data.
011: Recovered clock (RCLK).
100: LEXZ indication.
101: LBPV indication.
110: LEXZ + LBPV indication.
111: LLOS indication.
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 RDn, 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.
00: Receive Single Rail NRZ Format system interface. The data is output on RDn 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.
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.
