description

The TCM29C23 and TCM129C23 are single-chip PCM codecs (pulse-code-modulated encoders and

decoders) and PCM lines filters. These devices provide all the functions required to interface a full-duplex

(4-wire) voice telephone circuit with a TDM (time-division-multiplexed) system. Primary applications include

digital encryption systems, digital voice-band data storage systems, digital signal processing, and mobile

telephones.

These devices are designed to perform the transmit encoding (A/D conversion) and receive decoding (D/A

conversion) as well as the transmit and receive filtering functions in a pulse-code-modulated system. They are

intended to be used at the analog termination of a PCM line or trunk.

The TCM29C23 and TCM129C23 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 supervision information.

TheTCM29C23ischaracterizedforoperationfrom0°Cto70°C. TheTCM129C23ischaracterizedforoperation

from –40°C to 85°C.

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.

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.
