Hli located an interesting app note from Cypress called “Mixed Signal Circuit Board Layout Considerations”. “It discusses how to layout a board to have good analog performance, even if you have digital stuff on the same board. Some parts are specific for the Cypress PSoCs, but much of the advice is applicable generally.
The PSoCs are interesting here because they mix a CPU (up to Cortex-M3) together with CPLD capabilities together with programmable / reconfigurable analog components (DAC, up-to 20bits ADC, OpAmps, filters any many more) on a single chip.”
