AK4113VF

Overview

The AK4113VF is a 24-bit stereo digital audio receiver supporting sampling rates up to 216kHz. It features six receiver inputs and one transmission output, compatible with AES/EBU, IEC60958, S/PDIF, and EIAJ CP1201 standards. The device includes an integrated low jitter PLL with a lock range of 8kHz to 216kHz. Control is managed via a serial µP interface (I²C or 4-wire) or parallel pin strapping. Operating voltage ranges from 2.7V to 3.6V with 5V logic tolerance. It is housed in a 30-pin VSOP package.

Feature Summary

• Supports 6-channel receiver input and 1-channel transmission output
• Detects non-PCM bit streams including Dolby Digital and DTS-CD
• Includes Q-subcode buffer for CD applications
• Provides two master clock outputs (MCKO1/MCKO2)

Applications

• Digital Audio Interfacing
• Dolby Digital system solutions

Procurement Notes

Verify the specific suffix 'VF' corresponds to the 30-pin VSOP package and -40°C to +85°C operating temperature range as documented in the datasheet. Confirm that the I²C interface speed does not exceed the maximum specified limit of 400kHz during integration.

Selection Notes

Select this component when a multi-channel digital audio receiver with high-frequency support up to 216kHz is required. Ensure the design accommodates the 30-pin VSOP footprint and provides appropriate power supply decoupling for the 2.7V to 3.6V operating range.

Part Context

The AK4113VF belongs to the AK4113 series of digital audio receivers. It serves as an upgrade to the AK4112B, offering increased channel capacity (6 vs 4), wider PLL lock range (8-216kHz vs 22-108kHz), and additional detection features such as DTS-CD and DAT Start ID.

Replacement Considerations

The AK4112B is a related model but has incompatible control registers and fewer channels. Direct substitution requires verifying pin compatibility and reprogramming control settings due to functional differences.
