† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Voltage values for maximum ratings are with respect to VBB.
DescriptionThe TCM29C13, TCM29C14, TCM29C16,TCM29C17, TCM129C13, TCM129C14, TCM129C16, and TCM129C17 are single-chip PCM codecs (pulse-code-modulated encoders and decoders) and PCM line filters. 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
