In general, here is how I expect this project to go. Details will be added here as they develop. As each step happens, I'll add a Project Log.
Step 1: Required reading - data sheet and Eval board description. A Teensy 3.X will be used to do the configuration, clocking, and the sampling. The design used in the Spectrophotometer will be copied for the output; the input side will be new.
Design question: Should inputs be single ended or differential?
Design question: How should the RCLK output be conditioned to use as a signal source?
Step 2: Introductory Experiments that I want to try on the first design. What features should the board have for these? This step also yields the test signals / noise source that will be used.
Step 3: Initial design. How to partition the design? Are pre-amp and filters separate boards? Design board(s) and order parts.
Step 4: Build and Test! What works and what doesn't? What can I learn about using quadrature?
Step 5: Let's build a milliohm meter! Seems like a worthy goal.
Step 6: Let's measure an LED's response (classic experiment)! Another worthy goal.
Step 7: Evaluate results and redesign as needed.
