TP13054BN

Codecs Overview

The TP13054BN 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 supply currents of 6 mA to 10 mA from both VCC and VBB rails. It supports master clock frequencies of 1.536 MHz, 1.544 MHz, or 2.048 MHz and bit clocks ranging from 64 kHz to 2.048 MHz. Characterized for an operating temperature range of –40°C to 85°C, it utilizes a 16-pin DW package.

Codecs Feature Summary

• Integrates complete PCM codec and line filtering systems on a single chip
• Supports μ-Law encoding and decoding standards
• Features TTL- or CMOS-compatible digital serial I/O interface
• Includes internal autozero circuitry and precision voltage reference

Codecs Applications

• Line interface for T1 carrier digital transmission systems
• Subscriber line concentrators in central office telephone systems
• Digital voice-band data-storage systems
• Digital signal processing applications

Codecs Procurement Notes

Verify the specific manufacturer source for the 'BN' suffix, as official datasheets list the standard part number as TP13054B. Confirm that the component matches the specified 16-pin DW surface-mount package and meets the –40°C to 85°C industrial temperature rating requirements before integration.

Codecs Selection Notes

Select this component for full-duplex voice telephone circuits interfacing with TDM systems. Ensure the design accommodates asynchronous or synchronous master clock configurations. Verify that the application does not require composite transmit signals below –55 dBm0 due to patented idle noise characteristics.

Codecs Part Context

The TP13054B belongs to the TP305xB family of monolithic serial interface codecs. It serves as an improved version of National Semiconductor devices and provides pin-for-pin compatibility with the TP3054B. The 'TP' prefix indicates the extended industrial temperature range variant compared to the commercial grade parts.

Codecs Replacement Considerations

The TP3054B is a direct pin-compatible replacement within the same family but is limited to the 0°C to 70°C temperature range. Other variants include the TP13057B and TP3057B, which utilize A-Law coding instead of μ-Law.
