Pin No.
RDn: Receive Data for Channel 0 ~ 16
When the receive system interface is configured to Single Rail NRZ Format mode, this multi-
plex pin is used as RDn.
The decoded NRZ data is updated on the active edge of RCLKn. The active level on RDn is
selected by the RD_INV bit (b3, RCF1,...).
When the receiver is powered down, RDn will be in High-Z state or low, as selected by the
RHZ bit (b6, RCF0,...).
RDPn: Positive Receive Data for Channel 0 ~ 16
When the receive system interface is configured to Dual Rail NRZ Format mode, Dual Rail RZ
Format mode or Dual Rail Sliced mode, this multiplex pin is used as RDPn.
In Receive Dual Rail NRZ Format mode, the un-decoded NRZ data is output on RDPn and
RDNn and updated on the active edge of RCLKn.
In Receive Dual Rail RZ Format mode, the un-decoded RZ data is output on RDPn and RDNn
and updated on the active edge of RCLKn.
In Receive Dual Rail Sliced mode, the raw RZ sliced data is output on RDPn and RDNn.
For Receive Differential line interface, an active level on RDPn indicates the receipt of a posi-
tive pulse on RTIPn and a negative pulse on RRINGn; while an active level on RDNn indi-
cates the receipt of a negative pulse on RTIPn and a positive pulse on RRINGn.
For Receive Single Ended line interface, an active level on RDPn indicates the receipt of a
positive pulse on RTIPn; while an active level on RDNn indicates the receipt of a negative
pulse on RTIPn.
The active level on RDPn and RDNn is selected by the RD_INV bit (b3, RCF1,...).
When the receiver is powered down, RDPn and RDNn will be in High-Z state or low, as
selected by the RHZ bit (b6, RCF0,...).
RDNn: Negative Receive Data for Channel 0 ~ 16
When the receive system interface is configured to Dual Rail NRZ Format mode, Dual Rail RZ
Format mode or Dual Rail Sliced mode, this multiplex pin is used as RDNn.
(Refer to the description of RDPn for details).
RMFn: Receive Multiplex Function for Channel 0 ~ 16
When the receive system interface is configured to Single Rail NRZ Format mode, this multi-
plex pin is used as RMFn.
RMFn is configured by the RMF_DEF[2:0] bits (b7~5, RCF1,...) and can indicate PRBS/ARB,
LAIS, LEXZ, LBPV, LEXZ+LBPV, LLOS, output recovered clock (RCLK) or XOR output of
positive and negative sliced data. Refer to Section 3.5.7.1 RMFn Indication for details.
The output on RMFn is updated on the active edge of RCLKn. The active level of RMFn is
always high.
When the receiver is powered down, RMFn will be in High-Z state or low, as selected by the
RHZ bit (b6, RCF0,...).
