AK4571VQ集成电路（IC）的编解码器规格书PDF中文资料

AK4571VQ属于集成电路（IC）的编解码器。由旭化成微电子株式会社制造生产的AK4571VQ编解码器编解码器是用于通过压缩和解压缩来转换数据的半导体器件。数据压缩可提高传输速度并减少存储空间。某些编解码器提供高达 32 位的分辨率，并且分别提供多达 6 个或 8 个模数转换器和数模转换器。除三角积分调制外，还有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 数据接口。

Overview:

AK4571 is built-in and 1ch A / D converter, a 2ch D / A converter 1 Chip 16bit CODEC. AK4571 has a USB I / F, via the USB bus To make the transfer of data. In one of the crystal, seven types of sampling It is possible to set the frequency, ADC, DAC independently operable is. PLL and for this, the transceiver, SIE (Serial Interface Engine), audio control circuit, FIFO, etc. has a built-in all.

Analog input, as well as with the first stage 20dB fixed amplifier, from + 24dB It has a variable that can be gain amplifier for each 1dB to -31dB. further, Analog input, mixing and D / A output, be analog output Is possible.
