Analog constraints are much different than digital ones. If you're expecting to do anything on the 18MHz range you wouldn't be looking at this product.

But in practice I'd doubt you would be using it for anything > 100kHz, maybe 1MHz. Which is absolutely fine for most applications this is intended.

If you're really targeting anything analog > 1MHz you really should know what you're getting into, and you wouldn't be looking at a board like this.
