TP13054ADW

Codecs Overview

The TP13054ADW is a monolithic serial interface combined PCM codec and filter manufactured by Texas Instruments. It integrates a single-chip pulse code-modulated encoder and decoder with PCM line filtering to interface full-duplex voice telephone circuits with time-division-multiplexed systems. The device operates on ±5 V supplies (VCC = 5 V ±5%, VBB = -5 V ±5%) and supports master clock frequencies of 1.536 MHz, 1.544 MHz, or 2.048 MHz. It utilizes a TTL- or CMOS-compatible digital interface with bit clocks ranging from 64 kHz to 2.048 MHz. Characterized for an operating temperature range of -40°C to 85°C, it features μ-Law encoding/decoding, active RC noise filters, and an internal precision voltage reference.

Codecs Feature Summary

• Integrates complete transmit and receive filtering functions including band-pass filtering for analog signals prior to encoding and after decoding.
• Provides μ-Law compatible coder and decoder functionality within a single-chip architecture.
• Features an internal autozero circuitry and precision voltage reference to maintain signal integrity.
• Supports both synchronous and asynchronous operation modes with flexible frame sync configurations.

Codecs Applications

• Line interface for digital transmission and switching of T1 carrier systems
• Subscriber line concentrators in PABX and central office telephone systems
• Digital-encryption systems requiring voice-band data processing
• Digital voice-band data-storage systems

Codecs Procurement Notes

Verify the specific suffix 'DW' corresponds to the 16-SOIC package and commercial/industrial temperature grade (-40°C to 85°C) as defined in the datasheet. Confirm that the component meets RoHS3 compliance standards. Check for end-of-life status or obsolescence notices from Texas Instruments before finalizing procurement plans.

Codecs Selection Notes

Select the TP13054ADW when industrial temperature performance (-40°C to 85°C) is required alongside μ-Law coding. Ensure the system design accommodates the ±5 V dual supply requirement. Verify compatibility with the target TDM system's master clock frequencies (1.536 MHz, 1.544 MHz, or 2.048 MHz) and bit clock rates.

Codecs Part Context

The TP13054A is part of the TP3054A family, which includes the TP3054A, TP3057A, and TP13057A. The 'TP13054A' designation specifically denotes the industrial temperature grade version characterized for -40°C to 85°C operation, whereas the 'TP3054A' is rated for 0°C to 70°C. All variants share pin-for-pin compatibility with National Semiconductor equivalents.

Codecs Replacement Considerations

Publicly confirmed substitutes include the TP3054ADW (commercial grade), TP13057BDW (A-Law industrial grade), and TP3057ADW (A-Law commercial grade). These parts are pin-compatible but differ in temperature rating or coding standard (μ-Law vs. A-Law).
