934 One-tile ADC
934 : One-tile ADC
- Author: Daniel S
- Description: This is the stand-in for my ADC ASIC design. Idea is to use a clamped ±3V sinudoid on an input pin which will be digitsed with this circuit.

How it works
This tile uses a DSP block to do this. (I'm not actually sure yet, just using this as a placeholder).
How to test
Apply a ±3V analogue signal of any shape to input pin 1. Enable input pin 2 to begin digitisation.
External hardware
A function generator is useful for testing.
