3.3.6.2 Transmit Single Ended Mode
Transmit Single Ended mode can only be used in 75
coaxial cable
applications.
In Transmit Single Ended mode, only Internal Impedance Matching is
supported. Internal Impedance Matching circuit uses an internal
programmable resistor (IM) only. The T_TERM[2:0] bits (b2~0, TCF0,...)
should be set to ‘011’. The output amplitude is 4.74 Vpp when PULS[3:0]
is ‘0001’ and the SCAL[5:0] bits (b5~0, SCAL,...) is ‘100001’.1
In Single Ended mode, special care has to be taken for termination
and overall setup. Refer to separate application note for details.
A 1:2 (step up) transformer should be used in application.
Figure-18 shows the connection for one channel.

In this mode, port protection
should be enhanced.
Note:
1. The waveform in this mode is not standard. However, if the arbitrary wave-
form generator is used, the waveform could pass the template marginally.
