AMD Discloses Initial Zen 2 Details

There is nothing analog about the IO die. It interfaces the memory, and the system's busses like PCIe. They are all digital.

Sorry, I've meant analog circuitry, which I've read again and again about on CPUs - see below as one example. And it was also mentioned in some articles about the IO die on Zen 2.

> Intel’s analog designers are responsible for creating circuits such as PLLs (for clocking) and PCIe (for I/O) that are critical for modern SoCs on a process that isn’t optimized for analog

Yeah, anything measured in GHz going off-chip is well into analog signal processing territory.
