寻找具有以太网输入和输出音频I2S信号能力的电路板

嗨，
请咨询您所在地区的FAE，他们可以帮助您解决此问题。
我猜ML506板有以太网输入和音频输出。
但请与FAE联系。

Hi,
 
Please consult the FAE's in your region who can help you out with this query. I guess ML506 board had the ethernet input and audio output. However check with the FAE's.  The contacts are here - http://www.xilinx.com/company/contact/auth-disti-table.htm
Thanks,
Anirudh

This one is also incorrect on the site, when you click the link at least.

我正在使用I2S IP内核直接从FPGA中取出它。
我在zc702板上用逻辑分析仪测试，现在信号被路由到定制板上的DAC并正常工作。
所以几乎任何评估板都可以，你需要三个或四个备用通用输出 - 只要银行电压适合你的I2S接收设备，GPIO接头，PMOD接头等都可以。
但即使不是逻辑电平转换器也可以使用。



以下为原文

I'm using an I2S IP core to get it straight out of the FPGA.  I did that on a zc702 board to test with a logic analyser, now the signals are routed to a DAC on a custom board and work fine.
 
So pretty much any eval board will be fine, you just need three or four spare general purpose outputs - GPIO headers, PMOD connectors etc. will all be fine as long as the bank voltage is ok for your I2S sink device. But even if not a logic level translator can be used.
 
 

我正在尝试使用J62接头的PMOD2引脚将PMODI2S DAC与ZC702板接口，并且正在生成信号。
pmod dac工作在3.3 V，这是给这些信号。
使用ILA核心检查这些信号，它显示正确。
但是使用逻辑分析仪检查时，信号没有正确生成。
此外，当连接到DAC时，不会播放预期的音频。
找不到解决方案。
可能是因为pmod2引脚并联连接到电路板的用户LED。
任何人都可以帮我找到解决方案。
或者，如果LED正在创建任何问题，有任何方法可以断开LED与pmod2引脚的连接。
需要解决方案。
提前致谢



以下为原文

I am trying to interface PMODI2S DAC with ZC702 board using PMOD2 pins of J62 header and the signals are being generated. The pmod dac works with 3.3 V, which is given to these signals. These signals are checked using the ILA core, it shows correct. But when checked using logic analyzer, signals are not properly generated. Also when connected to the DAC, the expected audio is not played. Could not find the solution. May be because the pmod2 pins are parallely connected to the user leds of the board.
 
Can anyone please help me find the solution. Or if the leds are creating any problem is there any way to disconnect the leds from the pmod2 pins. Need a solution.
 
Thanks in advance

使用示波器查看这些信号将显示它们是否满足有效逻辑电平或是否被LED拉低。
逻辑分析仪可能没有与DAC相同的逻辑阈值。
任何人都可以帮我找到解决方案。
或者，如果LED正在创建任何问题，有任何方法可以断开LED与pmod2引脚的连接。

我从'示波器开始，然后将LED从板上拉下来。
----------------------------是的，我这样做是为了谋生。

Looking at those signals with an oscilloscope will show whether they meet valid logic levels or if they are pulled down by the LEDs. A logic analyzer might not have the same logic thresholds as the DAC.

Can anyone please help me find the solution. Or if the leds are creating any problem is there any way to disconnect the leds from the pmod2 pins. Need a solution.

I'd start with the 'scope, and then yank the LEDs off the board.

我尝试使用SPARTAN 3E板，它工作正常。
逻辑分析仪也显示正确的信号，音频输出也很好。
但同样不是ZC702板。
我认为LED正在制造问题。
如何将LED从板上拉下来。
你的意思是从车上取下LED吗？



以下为原文

I tried the same using SPARTAN 3E board, it worked fine. The logic analyzer also showed correct signals, audio ouput also played fine. But same is not wroking with the ZC702 board. I suppose that the leds are creating problem. How to yank the leds off the board. Do you mean to physically remove the leds off the board?

是的，拿一把烙铁就可以了。

Yes, get a soldering iron and have at it.

如果您碰巧有Zedboard，它上面有一个goodAudio编解码器（ADAU1761）。
它将为您节省使用外部组件的头脑。
此外，还有一个很好的教程，介绍如何使用它并配置其ADC和DAC。

If you happen to have a Zedboard it has a good Audio codec (ADAU1761)on it. It will save you the headahce of using external components. Also there is a nice tutorial on how to use it and configure its ADCs and DACs .
