LC89058W-E

Audio Special Purpose Overview

The LC89058W-E is a digital audio interface receiver IC designed to demodulate signals according to IEC60958/61937 and JEITA CPR-1205 standards. It supports sampling frequencies from 32kHz to 192kHz and operates on a single 3.3V power supply with 5V-tolerant TTL inputs. The device features a built-in PLL with false lock prevention, an oscillation amplifier for quartz resonators, and seven digital data input pins. It provides multiple clock outputs (512fs to 1/4fs) and supports multi-channel transfer via master/slave functionality. Packaged in a 48-SQFP format, it is optimized for AV amplifiers and receivers.

Audio Special Purpose Feature Summary

• Demodulates S/PDIF and serial data at sampling frequencies of 32kHz to 192kHz.
• Built-in PLL false lock prevention circuit and oscillation amplifier for quartz resonator.
• Seven digital data input pins: one coaxial compatible and six 5V-tolerable TTL level inputs.
• Supports multi-channel transfer using master/slave function and up to four chip addresses.

Audio Special Purpose Applications

• AV amplifiers
• Audio receivers
• Digital audio systems

Audio Special Purpose Procurement Notes

Verify component status as the LC89058W-E is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure that any replacement components maintain compatibility with existing PCB layouts and microcontroller interfaces, particularly regarding pin functions and register configurations.

Audio Special Purpose Selection Notes

Select this component for applications requiring digital audio interface reception compliant with IEC60958/61937 standards. It serves as a direct replacement for the LC89057W-VF4A-E, though circuit pattern reviews may be necessary due to differences in pin functionalities, specifically pins 44 to 48. Ensure the design accommodates the 48-SQFP package and 3.3V supply requirements.

Audio Special Purpose Part Context

The LC89058W-E belongs to the LC89058W series of audio DSPs manufactured by onsemi. It is part of a family of specialized audio integrated circuits designed for high-performance digital audio processing. This specific model focuses on demodulation capabilities, distinguishing itself from previous models by removing modulation functions while enhancing clock output flexibility and input detection ranges.

Audio Special Purpose Replacement Considerations

The LC89058W-E is documented as a replacement for the LC89057W-VF4A-E. When substituting, review the printed circuit board design, especially for pins 44 to 48, as their I/O functionality settings differ based on the INT pin configuration. Register maps also show changes, with some commands removed and new ones added.
