Analog
output
Transmit Bipolar Tip for Channels 1–16.
These pins are differential
line driver tip outputs. These pins can be high impedance if pin OE is
low. When “1” is set in the Output Enable Register
OE
bit, the
associated TTIPn pin will be enabled when the OE pin is high. The
differential outputs of TTIPn and TRINGn can provide internal
matched impedance for E1 75 , E1 120 , T1 100 , or J1 110 .
If the TCLK input for a given LIU is held low for 64 MCLKs, that LIUs
transmitter is powered down and the TTIP/TRING outputs are high
impedance.
Analog
output
Transmit Bipolar Ring for Channels 1–16.
These pins are
differential line driver ring outputs. These pins can be high impedance
if pin OE is low. When “1” is set in the Output Enable Register
OE
bit,
the associated TRINGn pin will be enabled when the OE pin is high.
The differential outputs of TTIPn and TRINGn can provide internal
matched impedance for E1 75 , E1 120 , T1 100 , or J1 110 .
If the TCLK input for a given LIU is held low for 64 MCLKs, that LIUs
transmitter is powered down and the TTIP/TRING outputs are high
impedance.
Analog
input
Receive Bipolar Tip for Channels 1–16.
Receive analog input for
differential receiver. Data and clock are recovered and output at
RPOS/RNEG and RCLK pins respectively. The differential inputs of
RTIPn and RRINGn can provide internal impedance matching with
external resistance for E1 75 , E1 120 , T1 100 , or J1 110 .
