TxON
I
Transmitter ON Input :
This pin is active only when the corresponding TxON bit is set.
Table below shows the status of the transmitter based on theTxON bit and TxON
pin settings.
NOTES:
1. This pin will be active and can control the TTIP and TRING outputs only
when the TxON_n bits in the channel register are set .
2. When Transmitters are turned off the TTIP and TRING outputs are Tri-
stated.
3. This pin is internally pulled up.

TxCLK_0
TxCLK_1
I
Transmit Clock Input for TPOS and TNEG - Channel 0:
Transmit Clock Input for TPOS and TNEG - Channel 1:
The frequency accuracy of this input clock must be of nominal bit rate ± 20 ppm.
The duty cycle can be 30%-70%.
By default, input data is sampled on the falling edge of TxCLK when input data
is changing on the rising edge of TxCLK..

TNEG_0
TNEG_1
I
Transmit Negative Data Input - Channel 0:
Transmit Negative Data Input - Channel 1:
In Dual-rail mode, these pins are sampled on the falling or rising edge of
TxCLK_n
NOTE: These input pins are ignored and must be grounded if the Transmitter
Section is configured to accept Single-Rail data from the Terminal Equipment.
