Hello Charles,
I have attached the user guide that details how to use the serial ports for an I2S signal. You can find it on page 5 under the heading "External Digital Input". This shows you how to set the registers up and also where the signal show…
Hello,
In the BOM for EVAL-ADAU1701MINIZ, (see atatched PDF, page 11 of 12) according to the description of crystal Y1 in this page, load capacitance is 18pF. However, the provided part number Abracon ABM3B-12.288MHZ-10-1-U-T has a load capacitance spec…
Hi Mike,
You are correct, ADI's AEC algorithm for SigmaDSP is only supported on the ADAU145x and ADAU146x processors.
Unfortunately the ADAU1701 will not support our AEC algorithm. The AEC algorithm relies heavily on frequency domain processing, which…
just to add my $0.02 ...
Im also investigating ADAU1701 I2S with a CODEC. I plain to run the ADAU1701 as a slave. (short on IO)
12.288MHz OSC on the CODEC, it has a MCLK OUT which I will connect to the ADAU1701 MCLKI.

hi Xinshuwei,
ADI没有这样的针对语音增强的算法模块可提供给客户，但我们有些方案公司有这样的模块可以有贘提供给终端客户。
比如附件里的韩国第三方EXPAMEDIA就有关于语音增加，MP3音质提升，虚拟环绕等算法。他们在中国也有联系人的。
如果你有兴趣，可以直接发邮件联系他们。

Hi,
I'm try to design an I2S communication system with a uC and ADAU1701.
uC has to be master in I2S and obtain the digital audio from ADAU1701.
ADAU1701 has an crystal of 12.288MHz as source clock, because fs=48KHz.
In order to use Audio Digital…
I have a ADAU1701 eval board, and when I unplug the USB , I have to "run link compile" to reactivate the ADAU1701
How can I make the ADAU1701 save the data after power down ?
Can I add a ADC chip to one of the GPIO pins of the ADAU1701 to get more analog inputs on the ADAU1701 ?
I want to add more analog inputs to the ADAU1701 to control pots and switches would this work ?
Thanks in advance
Hi Lars,
Thanks for the reply.
I am trying to add a device tree node(sound) for adau1701 machine driver in the device tree file of the iMX-sabrelite board.Could you tell me the name of the file where you have done it for linux/bfin-eval-adau1701.c at…
