LC89075W-H

Audio Special Purpose Overview

The LC89075W-H is a digital audio interface receiver and stereo analog-to-digital converter (ADC) designed for AV receivers, digital TVs, and DVD recorders. It demodulates IEC60958/61937 and JEITA CPR-1205 signals at sampling frequencies up to 192kHz. The integrated 24-bit ΔΣ stereo ADC supports single-ended inputs with sampling rates up to 96kHz. An internal audio selector manages up to 8-channel data routing. Supply voltages are 4.5V–5.5V for the ADC analog section and 3.0V–3.6V for digital and PLL sections. The device operates within a temperature range of -30°C to 85°C.

Audio Special Purpose Feature Summary

• S/PDIF demodulation supporting IEC60958/61937 and JEITA CPR-1205 standards with reception frequencies from 32kHz to 192kHz.
• 24-bit stereo ΔΣ ADC with built-in PGA (-4.5dB to 6dB), soft mute, and anti-aliasing filter; supports 8kHz to 96kHz sampling.
• Audio selector capable of handling up to 8-channel data with configurable input/output line mappings.
• SPI microcontroller interface for system control and status monitoring.

Audio Special Purpose Applications

• AV receivers
• Digital televisions
• DVD recorders

Audio Special Purpose Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to discontinuation or obsolescence. Confirm package integrity upon receipt, as moisture sensitivity requires proper storage conditions. Ensure supply voltage sequencing matches datasheet requirements to prevent latch-up during power-up.

Audio Special Purpose Selection Notes

Select this component when a combined S/PDIF receiver and stereo ADC is required for multi-channel audio processing. Verify that the system can accommodate the separate 5V analog supply for the ADC section if the ADC function is utilized. Ensure the host MCU supports the SPI interface for configuration.
