DIYINHK XMOS USB: The “DXIO”
Straight from the eBay page [link]
I have to congratulate this Mr. diyinhk. He can non only produce designs with such speed, but can somehow price them so amazingly low. This new module is priced at $59.95 -Can’t resist not getting it!
- Latest XMOS chip that uses 48MHz oscillator (rather than the 13Mhz used by the older XMOS chip for the USB interface) – I believe this is the XS1-U chip with built-in USB interface [link]
- 6.5uVrms Ultralow noise LDO. -The TI LP5900 [link]. I believe (the 6-legged chip next to the USB connector).
- Solid ground plane (a must for high speed digital circuit)
- No Via in active circuit (via inductance always create jitter problem)
- FOX ultra low ppm oscillators and Murata capacitors sourced from Digikey USA. -The two Xpresso 22.579 2MHz and 24.576 MHz clocks. They are of different size which reminds me of user complaining when some of the Hiface interfaces were built with the smaller size oscillators. But the industry is moving away from 5×7 mm to 3×5 mm and there is no way back.
- Gold plated USB connector (Molex, FCI, or other -depends on stock)
- Compact size 50mm x 30mm. -That is even smaller than the Amanero which is 30×70 mm approx.
- Module is USB powered but the diyer expert can remove FB1 and use an external 5V PS to CN1 (warning: over-voltage or reverse-voltage can damage the XMOS chip immediately. Any modification will void item warranty)
- Can optionally install series resistor to I2S lines (by cutting the traces)
WINDOWS DRIVERS PROVIDED (NO DRIVER REQUIRED FOR MACS)
Looks like the first USB interface using the latest generation XMOS chip (XCORE USB) with built-in USB.
