Transmit Positive Data/NRZ data
This pin’s function depends on the input level.
NRZ = Low : Positive AMI data output
NRZ = High : NRZ data
Transmit Negative Data
This pin’s function depends on the input level.
NRZ = Low : Negative AMI data output
NRZ = High : Should be tied to VSS
Transmit Clock
TPDATA and TNDATA are sampled on the rising or falling edge of TCLK.
Sampling edge must be assigned by TCKPOL pin.
TCLK Polarity select.
TCKPOL=Low : Transmit data is sampled on the rising edge of TCLK.
TCKPOL=High : Transmit data is sampled on the falling edge of TCLK.

Transmit Tip / Ring Output
AMI signal output. Requires a 1:1CT transformer. Hi-Z when

Pulse Level Adjustment
Transmit pulse level can be adjusted by the external resister.
Normally 1.33k
is connected for DS3/STS-1 or 1.27k
for E 3.
If the signal power level is larger than a requirement, you can tweak
it by increasing the value of this resister.
NRZ mode Enable
Active High input enables NRZ data interface with TPDATA and RPDATA.

In NRZ mode, TNDATA should be tied to VSS and RNDATA indicates LCV.
Line Built Out
If LBO is set to High, Line Built Out function is enable.
