10 / 78 page  10 INDUSTRIAL TEMPERATURE RANGES OCTAL CHANNEL T1/E1/J1 LONG HAUL/SHORT HAUL LINE INTERFACE UNIT Notes: 1. The footprint ‘n’ (n = 1~8) represents one of the eight channels. 2. The name and address of the registers that contain the preceding bit. Only the address of channel 1 register is listed, the rest addresses are represented by ‘...’. Users can find these omitted addresses in the Register Description section. 2 PIN DESCRIPTION Table-1 Pin Description Name Type Pin No. Description PQFP208 PBGA208 Transmit and Receive Line Interface TTIP1 TTIP2 TTIP3 TTIP4 TTIP5 TTIP6 TTIP7 TTIP8 TRING1 TRING2 TRING3 TRING4 TRING5 TRING6 TRING7 TRING8 Output Analog 164 177 184 197 64 77 84 97 163 178 183 198 63 78 83 98 A13 A8 C8 A3 T3 P8 T8 T13 B13 B8 D8 B3 R3 N8 R8 R13 TTIPn1/TRINGn: Transmit Bipolar Tip/Ring for Channel 1~8 These pins are the differential line driver outputs and can be set to high impedance state globally or individually. A logic high on THZ pin turns all these pins into high impedance state. When THZ bit (TCF1, 03H...)2 is set to ‘1’, the TTIPn/TRINGn in the corresponding channel is set to high impedance state. In summary, these pins will become high impedance in the following conditions: • THZ pin is high: all TTIPn/TRINGn enter high impedance; • THZn bit is set to 1: the corresponding TTIPn/TRINGn become high impedance; • Loss of MCLK: all TTIPn/TRINGn pins become high impedance;· • Loss of TCLKn: the corresponding TTIPn/TRINGn become HZ (exceptions: Remote Loopback; Transmit internal pattern by MCLK); • Transmitter path power down: the corresponding TTIPn/TRINGn become high impedance; • After software reset; pin reset and power on: all TTIPn/TRINGn enter high impedance.
