TP3054ADW

Codecs Overview

The TP3054ADW is a monolithic serial interface combined PCM codec and filter manufactured by Texas Instruments. It integrates transmit high-pass and low-pass filtering, receive low-pass filtering with (sin x)/x correction, active RC noise filters, and μ-Law compatible coder/decoder functions. The device operates on ±5 V supplies with typical active power consumption of 50 mW and standby power of 3 mW. It features an internal precision voltage reference and autozero circuitry. The component utilizes a TTL- or CMOS-compatible digital interface and is housed in a 16-SOIC package.

Codecs Feature Summary

• Integrates complete PCM codec and line filtering functions for full-duplex voice telephone circuits
• Supports μ-Law encoding and decoding with automatic power-down capabilities
• Includes internal precision voltage reference and autozero logic for signal stability

Codecs Applications

• Line interface for T1 carrier systems
• PABX and central office telephone systems
• Subscriber line concentrators
• Digital-encryption systems
• Digital voice-band data-storage systems

Codecs Procurement Notes

Verify the specific revision level against the SCTS026C datasheet to ensure compatibility with existing system timing requirements. Confirm that the ±5 V supply rails are stable within the recommended operating conditions before integration. Check for end-of-life status as this component may be discontinued.

Codecs Selection Notes

Select the TP3054ADW when μ-Law coding is required for North American T1 applications. Ensure the design accommodates the 16-SOIC surface-mount package dimensions. Verify that the master clock frequencies align with the 1.536 MHz or 1.544 MHz standards supported by this variant.

Codecs Part Context

This component belongs to the TP3054A family, which also includes the A-Law variant TP3057A. It serves as an improved version of earlier National Semiconductor designs. The 'DW' suffix indicates the 16-SOIC package type suitable for surface-mount assembly.

Codecs Replacement Considerations

The TP3054ADW is pin-for-pin compatible with the National Semiconductor TP3054A. Designers should verify that any substitute components maintain the same serial interface timing and ±5 V operation characteristics.
