Re: ASRC Custom Sample Rate

The input is 42 kHz and the output will be generated at 48 kHz. The output clock can be derived from / driven by the input at 8/7, so synchronous is fine. But I don't see any option to put a ratio like 8/7 in the SRC library... am I missing something?

ASRC Custom Sample Rate

I have an application where I need to convert from a custom sample rate (42 kHz) to a standard sample rate (either 44.1 kHz or 48 kHz). Can I use the SRC library to do this? 44.1/42 is about 5%, which is more than the 10,000 ppm limit specified for ASRC. Maybe this can be accomplished by modifying t...

Does anyone know where an Explorer board or other reference design for XS3 / xcore.ai can be purchased?

Universal "XPort" header for XS2 development board

Hi All, I am working on a series of development boards for XS2 series MCUs. I am for them to be well under $100 and as flexible as possible. I have a sort of universal "port" header that each board will feature, depending on the number of cores and a few other things. It is designed to bre...

New XCORE.AI Chips (XS3) Now Listed on futureelecronics.com

I happened to notice that the new XCORE.AI Chips (XS3 architecture) are now listed on futureelectronics.com. They are not yet "in stock", but you can see the expected prices anyway. I wish they had an ETA, but no sign yet. Sadly, minimum order quantities (MOQ) vary from 152 to 416... maybe...

Re: new xcore.ai - more details?

In the Linley report it seems to indicate the chip has 4 xCONNECT links, which would enable scalability well beyond two chips. That would be huge. Any idea if these links are compatible with xCORE-200 links? That would enable use of an xCORE-200 co-processor to host RGMII, additional USB, or lots of...

Re: 1.8V VDDIO Level in XCORE-200

I've recently been thinking about the same question. I am considering using an xCORE-200 series device with an external PSRAM memory which operates at 1.8 VIO. I found the following quote in the xCORE-200-* datasheets: "Separate I/O supplies are provided for the left, top, and right side of the...
