AKM 产品 音频组件 数字音频接口
Digital Audio Interfaces
大多数情况用AK4118只是做数字接收使用，但实际上AK4118还可以做数字发送用（I2S转SPDIF）
输入信号：I2S（标准I2SThe AK410X/1X series is a 24-bit digital audiotransmitters/transceivers/receivers. The channel status supportsboth consumer and professional formats and the AK410X/1X series hasautomatic detect function of Non-PCM data streams such as AC-3 andMPEG, capable to realize a AC-3 system with a multi-channeledCODEC. Dedicated parallel pins or serial µP interface is availablefor setting the device. The AK410X/1X series is housed in a smallpackage, saving board space.

AKM’s audio D/A converters (DACs) provide solutions for high audio system with the original digital-analog mixingtechnology.
They are used in variety of applications such as AV receivers,set-top boxes, speaker systems, digital TVs and car-entertainmentsystems, contributing to the sound and power consumptionimprovements and reducing externalparts.同轴光纤AES的信号锁定以后可显示当前采样率！板子带断电记忆功能，下次通电会自动选择上次使用的通道！同轴、光纤、AES支持的信号范围：16-24bit32-192K采样率！一路光纤加一路同轴输入（同轴或光纤）。支持16-24bit，32K-192K采样率SPDIF信号DAC芯片采用CS4398，Cirruslogic 动态达到120DB，失真加噪声极低-107DB，远超过一些低端的TDA1543类的DAC，也比PCM1793的指标为，是AD1955，AK4399同级别的DAC。
