TRANSMIT PATH LINE INTERFACE
The transmit line interface consists of TTIPn pin and TRINGn pin. The
impedance matching can be realized by the internal impedance matching
circuit or the external impedance matching circuit. If T_TERM[2] is set to
‘0’, the internal impedance matching circuit will be selected. In this case,
the T_TERM[1:0] bits (TERM, 1AH...) can be set to choose 75
, 100 ,
110
or 120 internal impedance of TTIPn/TRINGn. If T_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 imped-
ance matching. For T1/J1 mode, the external impedance matching circuit
forthetransmitterisnotsupported.Figure-9showstheappropriateexternal
components to connect with the cable for one channel. Table-14 is the list
of the recommended impedance matching for transmitter.
The TTIPn/TRINGn can be turned into high impedance globally by pull-
ing THZ pin to high or individually by setting the THZ bit (TCF1, 03H...) to
‘1’. In this state, the internal transmit circuits are still active.
Besides, in the following cases, TTIPn/TRINGn will also become high
impedance:
Loss of MCLK: all TTIPn/TRINGn pins become high impedance;
Loss of TCLKn: corresponding TTIPn/TRINGn become HZ (excep-
tions: Remote Loopback; Transmit internal pattern by MCLK);
Transmit path power down;
After software reset; pin reset and power on.
Note: The precision of the resistors should be better than ± 1%
3.2.5
TRANSMIT PATH POWER DOWN
The transmit path can be powered down individually by setting the
T_OFF bit (TCF0, 02H...) to ‘1’. In this case, the TTIPn/TRINGn pins are
turned into high impedance.
