Line Interface
RTIPn
RRINGn
(n=0~15)
Input
L3, M3, N3, P3, R3, R20, P20, N20,
K20, J20, H20, G20, G3, H3, J3, K3

RTIPn / RRINGn: Receive Bipolar Tip/Ring for Channel 0 ~ 15
The receive line interface supports both Receive Differential mode and Receive Single Ended
mode.
In Receive Differential mode, the received signal is coupled into RTIPn and RRINGn via a 1:1
transformer or without a transformer (transformer-less).
In Receive Single Ended mode, RRINGn should be left open. The received signal is input on
RTIPn via a 2:1 (step down) transformer or without a transformer (transformer-less).
These pins will become High-Z globally or channel specific in the following conditions:
Global High-Z:
- Connecting the RIM pin to low;
- Loss of MCLK
- During and after power-on reset, hardware reset or global software reset;
Per-channel High-Z
- Receiver power down by writing ‘1’ to the R_OFF bit (b5, RCF0,...)

L22, J22, G22, E22, C1, E1, G1, J1
TTIPn / TRINGn: Transmit Bipolar Tip /Ring for Channel 0 ~ 15
The transmit line interface supports both Transmit Differential mode and Transmit Single
Ended mode.
In Transmit Differential mode, TTIPn outputs a positive differential pulse while TRINGn out-
puts a negative differential pulse. The pulses are coupled to the line side via a 1:2 (step up)
transformer or without a transformer (transformer-less).
In Transmit Single Ended mode, TRINGn should be left open (it is shorted to ground inter-
nally). The signal presented at TTIPn is output to the line side via a 1:2 (step up) transformer.
These pins will become High-Z globally or channel specific in the following conditions:
Global High-Z:
- Connecting the OE pin to low;
- Loss of MCLK;
- During and after power-on reset, hardware reset or global software reset;
Per-channel High-Z
- Writing ‘0’ to the OE bit (b6, TCF0,...) 2;
- Loss of TCLKn in Transmit Single Rail NRZ Format mode or Transmit Dual Rail NRZ
Format mode, except that the channel is in Remote Loopback or transmit internal pat-
tern with XCLK 3;
- Transmitter power down by writing ‘1’ to the
T_OFF bit (b5, TCF0,...);
- Per-channel software reset;
- The THZ_OC bit (b4, TCF0,...) is set to ‘1’ and the transmit driver over-current is
detected.
Note:
1. The pin number of the pins with the footnote ‘n’ is listed in order of channel (CH0 ~ CH15).
2. The content in the brackets indicates the position and the register name of the preceding bit. After the register name, if the punctuation ‘,...’ is followed, this bit is in a per-channel register.
The addresses and details are included in Chapter 5 Programming Information.
3. XCLK is derived from MCLK. It is 1.544 MHz in T1/J1 mode or 2.048 MHz in E1 mode.
