8.2 Detailed Pin Descriptions
Table 8-2. Detailed Pin Descriptions
n=1,2,3,4 (port number); Ipu (input with pullup), Oz (output tri-stateable) (needs an external pullup or pulldown resistor to keep from floating), Oa
(Analog output), Ia (analog input), IO (Bidirectional inout); all unused input pins without pullup should be tied low.

Transmit Line Clock Output
TLCLKn: This signal is available when the transmit line interface pins are enabled
(PORT.CR2.TLEN). This clock is typically used as the clock reference for the TDATn and
TNEG signals, but can also be used as the reference for the TSOFIn, TSERn, and TSOFOn /
TDENn signals.
This output signal can be inverted.

Transmit Positive AMI / Data Output
TPOSn: When the port line interface is configured for B3ZS, HDB3 or AMI mode and the
transmit line interface pins are enabled (PORT.CR2.TLEN), a high on this pin indicates that a
positive pulse should be transmitted on the line. The signal is updated on the positive clock
edge of the referenced clock pin if the clock pin signal is not inverted, otherwise it is updated on
the falling edge of the clock. The signal is typically referenced to the TLCLKn line clock output
pins, but it can be referenced to the TCLKOn, TCLKIn, RLCLKn or RCLKOn pins. This output
signal can be disabled when the TX LIU is enabled.
This output signal can be inverted.
TDATn: When the port line interface is configured for UNI mode and the transmit line interface
pins are enabled (PORT.CR2.TLEN), the un-encoded transmit signal is output on this pin. The
signal is updated on the positive clock edge of the referenced clock pin if the clock pin signal is
not inverted, otherwise it is updated on the falling edge of the clock. The signal is typically
referenced to the TLCLK line clock output pins, but it can be referenced to the TCLKOn,
TCLKIn, RLCLKn or RCLKOn pins
This output signal can be inverted.
o
o
Transmit Negative AMI / Line OH Mask
TNEGn: When the port line is configured for B3ZS, HDB3 or AMI mode and the transmit line
interface pins are enabled (PORT.CR2.TLEN), a high on this pin indicates that a negative pulse
should be transmitted on the line. The signal is updated on the positive clock edge of the
referenced clock pin if the clock pin signal is not inverted, otherwise it is updated on the falling
edge of the clock. The signal is typically referenced to the TLCLKn line clock output pins, but it
can be referenced to the TCLKOn, TCLKIn, RLCLKn or RCLKOn pins.
This output signal can be inverted.

Transmit Positive Analog
TXPn: This pin and the TXNn pin form a differential AMI output which is coupled to the
outbound 75Ω coaxial cable through a 2:1 step-down transformer
enabled when the TX LIU is enabled and the output is enabled to be driven. When it is not
enabled, it is in a high impedance state.

enabled, it is in a high impedance state.
