AK4363VF

ADCs/DACs - Special Purpose Overview

The AK4363VF is a stereo CMOS D/A Converter and Phase Locked Loop (PLL) designed for digital video broadcast set-top boxes and DVD applications. It features a 24-bit resolution with an integrated low-jitter analog PLL that generates selectable master clock frequencies locked to a 27MHz MPEG reference. The device supports sampling rates from 16kHz to 96kHz, offering dynamic ranges up to 102dB at 5V. It includes on-chip digital filters, eliminating the need for external anti-aliasing components. Control is managed via 3-wire serial or I2C bus interfaces, supporting multiple data formats including I2S.

ADCs/DACs - Special Purpose Feature Summary

• Stereo 24-bit Delta-Sigma DAC with 102dB Dynamic Range and 102dB S/N ratio at 5V

• Supports sampling frequencies of 16kHz, 22.05kHz, 24kHz, 32kHz, 44.1kHz, 48kHz, 64kHz, 88.2kHz, and 96kHz
• Selectable data input formats: LSB justified, MSB justified, and I2S

ADCs/DACs - Special Purpose Applications

• Digital video broadcast set-top box systems
• DVD audio playback devices
• Consumer electronics requiring high-fidelity stereo digital-to-analog conversion

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'VF' against the manufacturer's ordering guide to confirm package type and temperature range specifications. Ensure compatibility with the required control interface mode (3-wire serial or I2C) by checking the state of the I2C pin during system design. Confirm power supply requirements align with the 2.7V to 5.5V operating range specified in the datasheet.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a fully integrated DAC with an on-chip PLL is required to simplify board layout by removing external loop filter components. Choose the AK4363VF for applications needing support for standard audio sampling rates up to 96kHz. Consider the 24-pin VSOP package constraints and ensure the host controller supports either the 3-wire serial or I2C control protocol for register configuration.

ADCs/DACs - Special Purpose Part Context

The AK4363VF is part of the AK4363 family produced by Asahi Kasei Microsystems. The 'VF' suffix typically denotes the specific package variant and industrial temperature range (-40°C to +85°C). Related evaluation hardware, such as the AKD4363, is available for testing the functionality of this DAC and PLL combination in prototype designs.
