TP13057BDW

Codecs Overview

The TP13057BDW 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 an A-Law compatible coder and decoder. The device operates on ±5-V supplies and features a TTL- or CMOS-compatible digital interface. It is characterized for operation from -40°C to 85°C and is housed in a 16-SOIC package.

Codecs Feature Summary

• Integrates complete PCM codec and filtering systems including transmit and receive filtering functions
• Supports A-Law encoding and decoding standards
• Features internal autozero circuitry and precision voltage reference
• Includes power-down standby mode for reduced power consumption

Codecs Applications

• Line interface for digital transmission and switching of T1 carrier systems
• Subscriber line concentrators
• Digital voice-band data-storage systems
• Digital signal processing applications

Codecs Procurement Notes

Verify the specific suffix 'BDW' corresponds to the tape-and-reel packaging option when sourcing components. Confirm that the manufacturer product number matches the exact part designation required for your bill of materials. Ensure compatibility with existing design specifications before procurement.

Codecs Selection Notes

Select this component for designs requiring integrated A-Law PCM coding and filtering in a single chip. Consider the -40°C to 85°C operating temperature range for industrial environments. Verify that the system supports the required serial interface timing and master clock frequencies for proper synchronization.

Codecs Part Context

This device belongs to the TP305xB family of monolithic serial interface combined PCM codecs and filters. It serves as an improved version of earlier National Semiconductor models, offering pin-for-pin compatibility while providing enhanced performance characteristics for telecommunications applications.

Codecs Replacement Considerations

The TP3057BDW is functionally equivalent to the TP3057B series. Check for availability of alternative packages such as the DW or N variants if different mounting styles are required. Ensure any substitute maintains the same A-Law encoding capability and operating temperature range.
