Pin No.
TDn: Transmit Data for Channel 0 ~ 16
When the transmit system interface is configured to Single Rail NRZ Format mode, this multi-
plex pin is used as TDn.
TDn accepts Single Rail NRZ data. The data is sampled into the device on the active edge of
TCLKn.
The active level on TDn is selected by the TD_INV bit (b3, TCF1,...).
TDPn: Positive Transmit Data for Channel 0 ~ 16
When the transmit system interface is configured to Dual Rail NRZ Format mode or Dual Rail
RZ Format mode, this multiplex pin is used as TDPn.
In Transmit Dual Rail NRZ Format mode, the pre-encoded NRZ data is input on TDPn and
TDNn and sampled on the active edge of TCLKn.
In Transmit Dual Rail RZ Format mode, the pre-encoded RZ data is input on TDPn and TDNn.
The line code is as follows (when the TD_INV bit (b3, TCF1,...) is ‘0’):
The active level on TDPn and TDNn is selected by the TD_INV bit (b3, TCF1,...).
TDNn: Negative Transmit Data for Channel 0 ~ 16
When the transmit system interface is configured to Dual Rail NRZ Format mode, this multi-
plex pin is used as TDNn.
(Refer to the description of TDPn for details).
TMFn: Transmit Multiplex Function for Channel 0 ~ 16
When the transmit system interface is configured to Single Rail NRZ Format mode or Dual
Rail RZ Format mode, this multiplex pin is used as TMFn.
TMFn is configured by the TMF_DEF[2:0] bits (b7~5, TCF1,...) and can indicate PRBS/ARB,
SAIS, TOC, TLOS, SEXZ, SBPV, SEXZ+SBPV, SLOS. Refer to Section 3.5.7.2 TMFn Indica-
tion for details.
The output on TMFn is updated on the active edge of TCLKn (if available). The active level of
TMFn is always high.
TCLKn: Transmit Clock for Channel 0 ~ 16
When the transmit system interface is configured to Single Rail NRZ Format mode or Dual
Rail NRZ Format mode, this multiplex pin is used as TCLKn.
TCLKn inputs a 1.544 MHz (in T1/J1 mode) or 2.048 MHz (in E1 mode) clock.
The data input on TDn (in Transmit Single Rail NRZ Format mode) or TDPn/TDNn (in Trans-
mit Dual Rail NRZ Format mode) is sampled on the active edge of TCLKn. The data output on
TMFn (in Transmit Single Rail NRZ Format mode) is updated on the active edge of TCLKn.
The active edge is selected by the TCK_ES bit (b4, TCF1,...).
TDNn: Negative Transmit Data for Channel 0 ~ 16
When the transmit system interface is configured to Dual Rail RZ Format mode, this multiplex
pin is used as TDNn.
(Refer to the description of TDPn for details).
Note:
* For Transmit Single Ended line interface, TRINGn should be open.
