Figure-6 Receive Differential Line Interface with Twist-
ed Pair Cable (transformer-less, non standard compli-
ant)
3.2.1.2 Receive Single Ended Mode
Receive Single Ended mode can only be used in 75
coaxial cable
applications.
In Receive Single Ended mode, only External Impedance Matching is
supported. External Impedance Matching circuit uses an external
resistor (Rr) only. The value of the resistor is 18.75
(see Figure-7 for
details) when the single end is connected with a 2:1 transformer or is 75
(see Figure-8 for details) when the single end is connected without a
transformer.
In Receive Single Ended mode, the RIM pin should be left open and
the configuration of the R_TERM[2:0] bits (b2~0, RCF0,...) is ignored.

1. Two Rr/2 resistors should be connected to VCOM[1:0] that are
coupled to ground via a 10
F capacitor, which provide 60
common mode input resistance.
2. In this mode, lightning protection should be enhanced.
3. The maximum input dynamic range of RTIP/TRING pin is
-0.3 V ~3.6 V (in line monitor mode it is -0.3 V ~ 2 V)
