STA120D13TR

Audio Special Purpose Overview

The STA120D13TR is a monolithic CMOS digital audio interface receiver manufactured by STMicroelectronics. It receives and decodes audio data compliant with AES/EBU, IEC 958, S/PDIF, and EIAJ CP-340/1201 standards. The device features an on-chip RS422 line receiver and a Phase-Locked Loop (PLL) for low-jitter clock recovery, providing a master clock output at 256 times the sample frequency. It supports supply voltages of 3.0V to 3.6V, typically 3.3V, with dynamic current consumption up to 15mA. The component operates within an ambient temperature range of -30°C to +85°C and is housed in a 28-pin SOIC package.

Audio Special Purpose Feature Summary

• Supports AES/EBU, IEC 958, S/PDIF, and EIAJ CP-340/1201 professional and consumer formats
• Integrated RS422 differential line receiver with Schmitt trigger hysteresis
• On-chip PLL recovers clock and synchronization signals with jitter attenuation starting at 25kHz
• Configurable serial port supporting 14 distinct audio data formats via M0-M3 pins

Audio Special Purpose Applications

• Consumer audio systems requiring S/PDIF decoding
• LCD TVs and monitors with digital audio inputs
• Audio processing units utilizing channel status reporting

Audio Special Purpose Procurement Notes

Verify the specific suffix 'D13TR' against the manufacturer's official documentation to confirm tape and reel packaging details. Ensure compatibility with the required 3.3V power supply domain and check that the 28-pin SOIC footprint matches the target PCB design constraints.

Audio Special Purpose Selection Notes

Select this component when a dedicated hardware solution for digital audio interface decoding is required without microprocessor intervention. It is suitable for designs needing direct access to channel status bits and error flags. Verify that the external loop filter components for the PLL meet the specified resistor and capacitor values for optimal jitter performance.

Audio Special Purpose Part Context

This part belongs to the STA120 family of digital audio interface receivers. The 'D' indicates the 28-pin SOIC package, while '13TR' denotes the tape and reel packaging configuration. It serves as a core component for extracting audio data and control information from standard digital audio transmission lines.

Audio Special Purpose Replacement Considerations

Consult the manufacturer's official substitution guide for verified equivalents. Generic replacements may not support the same specific serial port modes or channel status pin configurations.
