The TCM38C17IDL QCombo is a 4-channel  
single-chip PCM combo (pulse-code-modulated  
CODEC with a voice-band filtering) device. It  
performs the transmit encoding (A/D conversion)  
and receive decoding (D/A conversion), as well as the transmit and receive filtering functions required to meet  
CCITT G.711 and G.714 specifications in a PCM system. Each channel provides all the functions required to  
interface a full-duplex, 4-line voice telephone circuit with a TDM (time-division-multiplexed) system. The  
TCM38C17IDL is specifically designed for fixed-data-rate applications and is intended to replace four  
TCM29C13-type devices.  
Primary applications include digital transmission and switching of E1 carrier, PABX (private automatic branch  
exchange), and central office telephone systems and subscriber line concentrators. The device serves as the  
analog termination of a PCM line or trunk to the POTS (plain old telephone system) local-loop line.  
Other applications include any PCM digital-audio interface such as voice-band data storage systems and many  
digital signal processing applications that can benefit from the reduced footprint of a quad codec configuration  
and single-rail operation. Dynamic range and excellent idle-channel noise performance are maintained using  
the TI advanced 4Vt process technologies.  
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.

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
