Bit
Name
Description
7
RCKH
This bit determines the output on RCLKn when LLOS is detected. This bit is valid only when LLOS is detected and the AIS and
pattern generation is disabled in the receive path.
0: XCLK. (default)
1: High level.
6
RHZ
This bit determines the output of all receive system interfaced pins (including RDn, RDPn, RDNn, RMFn and RCLKn) when the
corresponding receiver is powered down.
0: Low level.
1: High-Z. (default)
5
R_OFF
This bit determines whether the receiver is powered down.
0: Normal operation. (default)
1: Power down.
4
R120IN
This bit is valid only when the receive line interface is in Receive Differential mode and per-channel internal impedance matching
configuration is enabled. This bit selects the internal impedance matching mode.
0: Partially Internal Impedance Matching mode. An internal programmable resistor (IM) and a value-fixed external resistor (Rr)
are used. (default)
1: Fully Internal Impedance Matching mode. Only an internal programmable resistor (IM) is used.
3
R_SING
This bit determines the receive line interface.
0: Receive Differential line interface. Both RTIPn and RRINGn are used to receive signal from the line side. (default)
1: Receive Single Ended line interface. Only RTIPn is used to receive signal. RRINGn should be left open.
2 - 0
R_TERM[2:0] These bits are valid only when impedance matching is configured on a per-channel basis. These bits select the impedance
matching mode of the receive path to match the cable impedance.
In Receive Differential mode:
000: The 100
internal impedance matching is selected for T1 100 twisted pair cable.
001: The 110
internal impedance matching is selected for J1 110 twisted pair cable.
010: The 120
internal impedance matching is selected for E1 120 twisted pair cable.
011: The 75
internal impedance matching is selected for E1 75 coaxial cable.
1XX: External impedance matching is selected for T1 100
, J1 110 , E1 120 twisted pair cable and E1 75 coaxial cable.
In Receive Single Ended mode, only External Impedance Matching is supported and the setting of these bits is a don’t-care.
