They are intended to be used at the analog termination of a PCM line or trunk. The TCM129C13, TCM129C14, TCM129C16, TCM129C17, TCM29C13, TCM29C14, TCM29C16, and TCM29C17 provide the band-pass filtering of the analog signals prior to encoding and after decoding. These combination devices perform the encoding and decoding of voice and call progress tones as well as the signaling and supervision information. The TCM29C13, TCM29C14, TCM29C16, and TCM29C17 are characterized for operation from 0 °C to 70°C. The TCM129C13, TCM129C14, TCM129C16, and TCM129C17 are characterized for operation from – 40 °C to 85 °C. functional block diagram Successive Approximation Buffer PWRO+ PWRO – GSR GSX ANLG IN – ANLG IN+ Transmit Section Receive Section SIGR† Control Section PDN Control Logic DCLKR PCM IN Input Register Digital- to-Analog Control Logic Reference Sample and Hold and DAC Analog- to-Digital Control Logic Gain Set Filter Reference FSX/TSXE Autozero Output Register TSX/DCLKX PCM OUT Comparator Sample and Hold and DAC Filter SIGX/ASEL CLKX CLKSEL ANLG LOOP† FSR/TSRE CLKR† ANLG GND DGTL GND VBB VCC ‡ † TCM29C14 and TCM129C14 only ‡ TCM29C13, TCM29C16, TCM29C17, TCM129C13, TCM129C16, and TCM129C17 only |
