Transmit ON/OFF
Upon power up, the transmitters are powered off. This bit is used
to turn the transmitter for this channel On or Off if the TxON pin is
pulled "High". If the TxON pin is pulled "Low", all 14 transmitters
are powered off.
0 = Transmitter is Powered OFF
1 = Transmitter is Powered ON
Loopback Diagnostic Select
LOOP[2:0] are used to select the loopback mode.
0XX = No Loopback
100 = Dual Loopback
101 = Analog Loopback
110 = Remote Loopback
111 = Digital Loopback
These Bits are Reserved.
Encoding/Decoding Select (Single Rail Mode Only)
0 = HDB3 (E1), B8ZS (T1)
1 = AMI Coding
Receive External Fixed Resistor
RxRES[1:0] are used to select the value for a high precision exter-
nal resistor to improve return loss.
00 = None
01 = 240 Ω
10 = 210 Ω
11 = 150 Ω
Insert Bipolar Violation
When this bit transitions from a "0" to a "1", a bipolar violation will
be inserted in the transmitted data from TPOS, QRSS/PRBS pat-
tern. The state of this bit will be sampled on the rising edge of
TCLK. To ensure proper operation, it is recommended to write a
"0" to this bit before writing a "1".
