I
Transmitter ON Input :
This input pin is used to either enable or disable the Transmit Output Driver.
"Low" - Disables the Transmit Output Driver. In this setting, the TTIP and
TRING output pins will be tri-stated.
"High" - Enables the Transmit Output Driver. In this setting, the TTIP and
TRING output pins will be enabled.
N
OTES
:
1.
Even when the XRT75L02 is configured in HOST mode, this pin will be
active. To enable software control of the Transmit Output Driver
output, pull this pin "High".
2.
When the Transmitter is turned off either in Host or Hardware mode,
the TTIP and TRing outputs are Tri-stated.
3.
This pins are internally pulled "High"

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..

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
N
OTE
:
These input pins are ignored and must be grounded if the Transmitter
Section is configured to accept Single-Rail data from the Terminal
Equipment.
