USB Digital Oscilloscope Project

Freddie Temperton has posted his design files of his USB Digital Oscilloscope Project. This is a new version and will use USB3 and a 1GSPS ADC. Freddie would like some feedback on the project from people who might be working on something similar.

Cypress FX2 (CY7C68013A-128AXC)

The chip is very easy to wire up, only requiring a 24MHz crystal, some EEPROM and reset switch. A few decoupling caps are needed, nothing substantial, but you will need to generate a 3V3 rail to power the core of the enhanced 8051 processor. This was generated with a small LT1763 fixed output regulator able to supply 500mA – more than enough to run the chip.”
