These devices provide all the functions required to interface a full-duplex (4-wire) voice telephone circuit with a time-division-multiplexed (TDM) system. These devices are intended to replace the TCM2910A or TCM2911A 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, TCM29C16A, TCM129C16, TCM129C17A 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 TCM29C13A, TCM129C13A 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 TCM29C14A, TCM129C14A DW PACKAGE (TOP VIEW) NC – No internal connection Copyright © 1996, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters. 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. |
