TCM29C16ADW

Codecs Overview

The TCM29C16ADW is an A-law and μ-law PCM codec manufactured by Texas Instruments. It operates at a clock frequency of 2.048 MHz and supports 13-bit or 14-bit resolution for voice signal processing. The device integrates analog-to-digital and digital-to-analog conversion capabilities within a single integrated circuit. It utilizes a standard serial interface compatible with common telecommunication protocols. The component is housed in a 20-pin plastic dual small-outline package (PDSO20) designed for surface-mount assembly.

Codecs Feature Summary

• PBX systems

Codecs Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official documentation to confirm pinout compatibility and electrical specifications. Ensure the PDSO20 package variant matches the target PCB footprint requirements. Cross-reference the revision level with current production status notices to avoid obsolete components during procurement.

Codecs Selection Notes

Select this component when A-law or μ-law encoding is required for standard telephony applications. Consider the 2.048 MHz clock speed constraint relative to the system timing architecture. Evaluate the power consumption characteristics against thermal management capabilities in the final enclosure design before integration.

Codecs Part Context

This part belongs to the TCM29C1x series of PCM codecs from Texas Instruments. The series includes variants such as TCM29C13, TCM29C17, and TCM29C16. These devices share similar functional architectures but differ in specific feature sets and package options. The TCM29C16ADW represents a specific configuration within this family optimized for standard voice channel processing.

Codecs Replacement Considerations

Check for direct substitutes like TCM29C16DW if the 'A' suffix denotes a specific temperature grade or revision. Verify pin-to-pin compatibility with other TCM29C1x series members before substitution.
