Transmit Bipolar Tip for Channel 1 to 8. These pins are
differential line-driver tip outputs. These pins will be high
impedance if pin OE is low or the corresponding OEB.OEBn bit is
high. If the corresponding clock TCLKn is low for 64 MCLKs, the
corresponding transmitter is put in power-down mode. The
differential outputs of TTIPn and TRINGn can provide internal
matched impedance for E1 75Ω, E1 120Ω, T1 100Ω, or J1 110Ω.
Transmit Bipolar Ring for Channel 1 to 8. These pins are
differential line-driver ring outputs. These pins will be high
impedance if pin OE is low or the corresponding OEB.OEBn bit is
high. If the corresponding clock TCLKn is low for 64 MCLKs, the
corresponding transmitter is put in power-down mode. The
differential outputs of TTIPn and TRINGn can provide internal
matched impedance for E1 75Ω, E1 120Ω, T1 100Ω, or J1 110Ω.
Receive Bipolar Tip for Channel 1 to 8. Receive analog input for
differential receiver. Data and clock are recovered and output at
RPOSn/RNEGn and RCLKn pins, respectively. The differential
inputs of RTIPn and RRINGn can provide internal matched
impedance for E1 75Ω, E1 120Ω, T1 100Ω, or J1 110Ω.
