TTIPn/TRINGn: Transmit Bipolar Tip/Ring for Channel 0~3
These pins are the differential line driver outputs. They will be in high-Z state if pin OE is low or the corre-
sponding pin TCLKn is low (pin OE is global control, while pin TCLKn is per-channel control). In host
mode, each pin can be in high-Z by programming a ‘1’ to the corresponding bit in register OE
RTIPn/RRINGn: Receive Bipolar Tip/Ring for Channel 0~3
These pins are the differential line receiver inputs.
TDn: Transmit Data for Channel 0~3
When the device is in Single Rail mode, the NRZ data to be transmitted is input on this pin. Data on TDn is
sampled into the device on the falling edges of TCLKn, and encoded by AMI or B8ZS/HDB3 line code
rules before being transmitted to the line.
BPVIn: Bipolar Violation Insertion for Channel 0~3
Bipolar violation insertion is available in Single Rail mode 2
14) with AMI enabled. A low-to-high transition on this pin will make the next logic one to be transmitted on
TDn the same polarity as the previous pulse, and violate the AMI rule. This is for testing.
TDPn/TDNn: Positive/Negative Transmit Data for Channel 0~3
When the device is in Dual Rail Mode, the NRZ data to be transmitted for positive/negative pulse is input
on this pin. Data on TDPn/TDNn are sampled on the falling edges of TCLKn. The line code in dual rail
mode is as the follow:
Pulling pin TDNn high for more than 16 consecutive TCLK clock cycles will configure the corresponding
channel into Single Rail mode 1
