AK4112BVF

Overview

The AK4112BVF is a digital audio receiver (DIR) supporting 96kHz sampling and 24-bit resolution. It features four receiver inputs and one through-transmission output, compatible with AES/EBU, IEC958, S/PDIF, and EIAJ CP1201 standards. The device includes a low-jitter analog PLL with a lock range of 22kHz to 108kHz and supports de-emphasis for 32kHz, 44.1kHz, 48kHz, and 96kHz. Operating on a 2.7V to 3.6V supply with 5V-tolerant input buffers, it is housed in a 28-pin VSOP package.

Feature Summary

• Supports AES/EBU, IEC958, S/PDIF, and EIAJ CP1201 formats
• Four receiver inputs (RX1-RX4) and one transmit output (TX)
• Low jitter Analog PLL with 22kHz-108kHz lock range
• Automatic Non-PCM bit stream detection (AC-3/MPEG)

Applications

• Digital audio interfacing systems
• AC-3 application solutions when combined with multi-channel codecs
• Consumer and professional digital audio equipment

Procurement Notes

Verify the specific suffix 'VF' against the manufacturer's current ordering guide to confirm package type and temperature grade. Confirm RoHS compliance status as product availability may vary by region. Check for obsolescence notices or end-of-life announcements prior to finalizing design-in decisions.

Selection Notes

Select this component for designs requiring multiple digital audio inputs and a single output within a compact footprint. Ensure the system clock requirements align with the available master clock outputs (MCKO1/MCKO2). Verify that the 5V tolerant input buffers meet the interface voltage levels of the connected source devices.

Part Context

The AK4112BVF belongs to the AK4112B series of high-feature 96kHz 24-bit digital audio receivers. It is designed to save board space with its small 28-pin VSOP package while providing comprehensive channel status decoding and error handling capabilities for robust digital audio signal processing.
