TPOS/TDATA Input
Transmit digital input pin. In dual rail mode, this pin is the transmit positive
data input. In single rail mode, this pin is the transmit non-return to zero (NRZ)
data input.
Transmit Negative Data Input
In dual rail mode, this pin is the transmit negative data input. In single rail
mode, this pin can be tied to ground.
Transmit Differential Tip Output
TTIP is the positive differential output to the line interface. Along with the
TRING signal, these pins should be coupled to a 1:2 step up transformer for
proper operation.
Transmit Differential Ring Output
TRING is the negative differential output to the line interface. Along with the
TTIP signal, these pins should be coupled to a 1:2 step up transformer for
proper operation.
In Circuit Testing
When this pin is tied "Low", all output pins are forced to "High" impedance for
in circuit testing.
N
Master Clock Input
This pin is used as the internal reference to the LIU. This clock must be
2.048MHz +/-50ppm.
OTE
: Internally pulled "High" with a 50KΩ resistor.
