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.

lineup

输出：一路同轴（spdif），一路光纤（spdif），一路i2s（标准i2s飞利浦格式）。i2s-in接口为i2s输入端口（gnddata bck lrck）.

 i2s-out接口为一路i2s输出信号（gnd data bck lrck mclk）.

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。
