Re: FIFO Reclock for i2s on input needed?

Hello and thank you for your detailed answer :) I think I will use an hardware ASRC such as the TI src4192. I Think this will give me much more flexibility and a secure usb interface, also I can use the usb host as playbak hardware, what is IMO the best solution in term of audio quality/jitter. Furt...

Re: FIFO Reclock for i2s on input needed?

Hello, I have an DSP which receives a stereo SPDIF Stream. It gives out an 6ch i2s stream. The xmos board is in slave mode ,so is the DAC. The clocks are recovered by the DSP from the SPDIF. The Problem is now,that I don't want to drive the xmos and the DAC attached to the xmos with the inferior jit...

FIFO Reclock for i2s on input needed?

Hello, I use the xu216 as an i2s-usb bridge. 8ch i2s in, 10ch i2s out. An external board is connected to the input of the XMOS Board with BCLK/LRCLK/DATA. I assume the oscillators from the external board are not the best. What I want to do now is using the XMOS as a slave and use the superior oscill...

Re: XMOS USB 10ch out

Hello, I do now own a JTAG3 Devic. It works. But I have a question regarding programming. My Board Vendor says, in order to work with XMOS USB Audio Software, I have to change a few lines, because of different port configuration. HOw can I do this? I have a picture of the port configuration: http://...

Re: XMOS USB 10ch out

o TDM8 input, 10ch i2s output. Is this possible? Yes, this should be fine. It will require 2 data lines but otherwise no problem. You could of course do all of the signal processing on XMOS too if you really wanted! A few dozen biquads will fit easily in a couple of logical cores. Nice! But I think...

Re: XMOS USB 10ch out

Okay, I have now a new approach. The first thing I've done, I ordered a JTAG3 USB Interface to flash a firmware. With external resamplers all Input Channels are now resampled to 48Khz. I need the asychronous sample rate converters because of different clocks and later the FIR convolution in the PC i...

Re: XMOS USB 10ch out

Thank You! A little more information about my requirements: I have 6ch (5.1) i2s coming from an other board. The board has its own MCLK. Furthermore I have 2ch i2s coming from an ADC (Phono). So it equals 8ch i2s Input. These inputs should now be available on the computer via usb for signal processi...

Hello!

Hello, My name is Jens. I'm currently experimenting with the XMOS chip and it's the first time creating something in the digital domain. I'm just not sure, if I've done the right choice. I need more channels than the 8ch I/O, instead 10ch out and 7 ch IN. That's why I am her, I want to learn the pro...
