RECEIVE PATH
The receive path consists of Receive Internal Termination, Monitor
Gain,Amplitude/WaveShapeDetector,DigitalTuningController,Adaptive
Equalizer, Data Slicer, CDR (Clock & Data Recovery), Optional Jitter
Attenuator, Decoder and LOS/AIS Detector. Refer to Figure-7.

RECEIVE INTERNAL TERMINATION
The impedance matching can be realized by the internal impedance
matching circuit or the external impedance matching circuit. If R_TERM[2]
is set to ‘0’, the internal impedance matching circuit will be selected. In this
case, the R_TERM[1:0] bits (TERM, 03H) can be set to choose 75
, 100
, 110 or 120 internal impedance of RTIP/RRING. If R_TERM[2] is
set to ‘1’, the internal impedance matching circuit will be disabled. In this
case, the external impedance matching circuit will be used to realize the
impedance matching. Figure-8 shows the appropriate external compo-
nents to connect with the cable. Table-11 is the list of the recommended
impedance matching for receiver.
