DUAL SERIAL LINK PHY MULTIPLEXER
Note that the loopback can also be activated remotely through inband bit
oriented codes.
TXDIS1:
The Transmit Disable 1 bit disables the high-speed outputs. If TXDIS1 is logic
one, the TXD1+/- outputs do not drive valid logic levels, but instead float.
TXDIS does not affect the differential output impedance; it is always within the
range specified in the D.C. Characteristics section..
TXDIS2:
The Transmit Disable 2 bit disables the high-speed outputs. If TXDIS2 is logic
one, the TXD2+/- outputs do not drive valid logic levels, but instead float.
TXDIS does not affect the differential output impedance; it is always within the
range specified in the D.C. Characteristics section.
RDIDIS1:
The RDI Disable 1 bit disables the automatic transmission of a RDI codeword
on TXD1+/-. If RDIDIS1 is logic zero, the declaration of LOS or LCD results
in the RDI codeword being transmitted in the BOC bit position .
Note that RDI can be sent manually by writing all zeros to the TXD1 Transmit
Bit Oriented Code register.
RDIDIS2:
The RDI Disable 2 bit disables the automatic transmission of a RDI codeword
on TXD2+/-. If RDIDIS2 is logic zero, the declaration of LOS or LCD results
in the RDI codeword being transmitted in the BOC bit position .
Note that RDI can be sent manually by writing all zeros to the TXD2 Transmit
Bit Oriented Code register.
