Overview
The AK4103AVF is a digital audio transmitter (DIT) supporting sample rates up to 192kHz. It accepts audio data and auxiliary information, biphase-encodes it, and drives the signal onto a cable via an on-chip RS422 line driver. The device supports AES3, IEC60958, S/PDIF, and EIAJ CP1201 standards. It operates on a 4.75V to 5.25V supply with an operating temperature range of -40°C to 85°C. The component features a 24-pin VSOP package and includes a 16-byte buffer for channel status and user bits.
Feature Summary
- Supports sampling rates from 28kHz to 192kHz
- Integrates RS422 line driver for professional and consumer interface standards
- Includes 16-byte on-chip buffer memory for Channel Status and User bits
- Generates CRCC codes and parity bits automatically
Applications
- Digital Audio Interfacing
- AES3/IEC60958/S/PDIF transmission systems
- Professional audio equipment
Procurement Notes
Verify the specific ordering suffix 'VF' corresponds to the 24-pin VSOP package and industrial temperature grade (-40°C to 85°C). Confirm that the datasheet revision MS0251-E-01 matches the required specifications for your design implementation.
Selection Notes
Select this component for applications requiring biphase encoding and transmission of stereo audio data up to 192kHz. Ensure the host system provides compatible MCLK frequencies (128fs, 256fs, 384fs, or 512fs) and supports the required serial control interface for register configuration.
Part Context
The AK4103AVF is part of the AK4103A series, which extends the functionality of the original AK4103 by adding CRCC generation capabilities in both synchronous and asynchronous modes. It serves as a monolithic CMOS solution for transmitting digital audio signals over balanced lines.
Replacement Considerations
The AK4103 is a predecessor model with a limited ambient temperature range of -10°C to 70°C and lacks hardware-controlled CRCC generation. Verify if the extended temperature range and enhanced CRCC features are required for the target application.
FAQ
What interface standards does the AK4103AVF support?
It supports AES3, IEC60958, S/PDIF, and EIAJ CP1201 interface standards.
How is the audio routing mode activated?
Audio routing mode (transparent mode) is activated when both the ANS pin and the TRANS pin are set to logic high.
What is the maximum master clock frequency supported?
The maximum master clock frequency is 27.648 MHz, depending on the selected clock mode (CKS1-0).
