They provide all the functions required to interface a full-duplex (4-wire) voice telephone circuit with a TDM (time-division-multiplexed) system, and are intended to replace the TCM2910A in tandem with the TCM2912C. Primary applications include: • Line interface for digital transmission and switching of T1 carrier, PABX, and central office telephone systems • Subscriber line concentrators • Digital-encryption systems • Digital voice-band data-storage systems • Digital signal processing 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VBB PWRO + PWRO – PDN DCLKR PCM IN FSR/TSRE DGTL GND VCC GSX ANLG IN – ANLG GND TSX/DCLKX PCM OUT FSX/TSXE CLKR/CLKX TCM29C16, TCM29C17, TCM129C16, TLC129C17 DW OR N PACKAGE (TOP VIEW) 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 VBB PWRO + PWRO – GSR PDN CLKSEL DCLKR PCM IN FSR/TSRE DGTL GND VCC GSX ANLG IN – ANLG IN + ANLG GND SIGX/ASEL TSX/DCLKX PCM OUT FSX/TSXE CLKR/CLKX TCM29C13, TCM129C13 DW OR N PACKAGE (TOP VIEW) 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 VBB PWRO + PWRO – GSR PDN CLKSEL ANLG LOOP SIGR DCLKR PCM IN FSR/TSRE DGTL GND VCC GSX ANLG IN – ANLG IN + ANLG GND NC SIGX/ASEL TSX/DCLKX PCM OUT FSX/TSXE CLKX CLKR TCM29C14, TCM129C14 DW PACKAGE (TOP VIEW) NC – No internal connection These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
