Can the MAX10 VCCIO supply be set at 2.7V?

I am looking to use the 10M02SCM153I7G which has a single supply (3V3). The system it interfaces with is running at 2V7. I noticed from the datasheet (Table 6) that the recommended power supplies for...

Yes, an interface operating at 50MHz should be fine at 2.7V. I don't think you'll see any problems. Single ended 2.5V I/O will quite happily go to that speed. So, the extra 200mV will only help.

Given the asynchronous interface, I'd suggest you could simply slow the interface down if you run into problems. However, like I've said, I don't think you will.

Removing clutter - regulators & level shifters - will make for a far more elegant design. I think you're heading in the right direction.

Cheers,
