TP3054WM-X/63

Codecs Overview

The TP3054WM-X/63 is a monolithic PCM CODEC/filter combo fabricated using TI's microCMOS process. It operates on ±5V supplies and supports μ-law encoding with a 16-pin package. The device integrates an input gain adjust amplifier, active RC pre-filter, switched-capacitor band-pass filter (200 Hz to 3400 Hz), companding coder, expanding decoder, low-pass filter with sin x/x correction, and a single-ended power amplifier. It requires master clocks of 1.536 MHz, 1.544 MHz, or 2.048 MHz and bit clocks from 64 kHz to 2.048 MHz. Typical active power consumption is 50 mW, while standby mode consumes approximately 3 mW.

Codecs Feature Summary

• Integrates complete transmit and receive filtering systems including high-pass, low-pass, and noise filters within a single CMOS component.
• Features TTL or CMOS compatible digital interfaces for flexible system integration.
• Includes internal precision voltage reference and auto-zero circuitry to maintain signal integrity.
• Supports automatic power-down functionality to minimize energy usage in idle states.

Codecs Applications

• D3 and D4 telephony applications
• CCITT standard compliant communication systems
• Line interface card circuit designs

Codecs Procurement Notes

Verify the specific suffix 'X' indicates extended temperature range operation (-40°C to +85°C) as defined by Texas Instruments. Confirm the '/63' designation corresponds to the tape and reel packaging format required for automated assembly processes. Cross-reference the datasheet revision SNOSBY2C to ensure compatibility with current design specifications.

Codecs Selection Notes

Select this component when designing systems requiring integrated μ-law PCM encoding and decoding with minimal external passive components. Ensure the application utilizes a ±5V power supply architecture. Verify that the available master clock frequencies align with the synchronous or asynchronous timing requirements of the host processor.

Codecs Part Context

This part belongs to the TP3054-X and TP3057-X Extended Temperature Serial Interface CODEC/Filter COMBO Family. The TP3054 variant specifically implements μ-law coding conventions, whereas the TP3057 variant utilizes A-law coding. Both share identical architectural features and pinouts but differ in their digital encoding standards.

Codecs Replacement Considerations

TP3057WM-X/63: Functionally similar but uses A-law encoding instead of μ-law.

Codecs FAQ

How does the device handle frame synchronization?

The device supports both short and long frame sync pulses. Short mode uses a pulse width of one bit clock period, while long mode requires three or more bit clock periods. The device automatically senses the pulse width upon power initialization.

What is the maximum overload level for the transmit section?

The precision voltage reference provides an input overload level (tMAX) of nominally 2.5V peak at the GSX output pin.

Can the device operate with asynchronous clocks?

Yes, separate transmit and receive master clocks can be applied. However, for best performance, MCLKR should be synchronous with MCLKX, which can be achieved by applying static logic levels to the MCLKR/PDN pin.
