These devices provide all the functions required to interface a full-duplex (2-wire) voice telephone circuit with a TDM (time-division-multiplexed) system. These devices are pin-for-pin compatible with the National Semiconductor TP3054B and TP3057B, respectively. Primary applications include: VBB ANLG GND VFRO VCC FSR DR BCLKR/CLKSEL MCLKR/PDN 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VFXI + VFXI – GSX TSX FSX DX BCLKX MCLKX Line interface for digital transmission and switching of T1 carrier,……
