Description

Transmit and Receive Line Interface

N5 TTIPn/TRINGn: Transmit Bipolar Tip/Ring for Channel 0~7

52

L5 These pins are the differential line driver outputs. They will be in high impedance state if pin OE

57

L10 is low or the corresponding pin TCLKn is low (pin OE is globe control, while pin TCLKn is per-

64 N10 channel control). In host mode, each pin can be in high impedance state by programming a “1” to

117 B10 the corresponding bit in Register OE1.
