Rx:
Fully Internal Impedance Matching mode. In this mode, there is no external resistor required. The R_TERM[2:0] bits (b2~0, RCF0,...)
setting is as follows: ‘000’ for T1 100
twisted pair cable, ‘001’ for J1 110 twisted pair cable, ‘010’ for E1 120 twisted pair cable and
‘011’ for E1 75
coaxial cable.
