DESCRIPTION
Transmit Positive Data/Transmit NRZ:
When ENDECB =’1’, a logic one on this pin generates a positive AMI
pulse on the coax. This pin should not be high at the same time that
corresponding TNEGx is high.
When ENDECB =’0’, data on this pin is encoded and converted into
positive and negative AMI pulses.
Transmit Negative Data:
When ENDECB =’1’, a logic one on this pin generates a negative AMI
pulse on the coax. This pin should not be high at the same time that
corresponding TPOSx is high.
When ENDECB =’0’, this pin is ignored.
Transmitter Clock Input:
This signal is used to latch the respective TPOSx and TNEGx signals
into the 78P2343JAT.
Line Out:
Differential AMI Outputs. Requires a 1:2CT center-tapped
transformer and a shunt termination resistor. See APPLICATION
INFORMATION section for more info.
