Which microcontrollers do boards using the Crystal Oscillator use?

Most are built on FPGA (3).

How big is a typical board using the Crystal Oscillator?

The median is 13 × 9.4 mm, and 0% are two-layer designs.

What is the most popular open source board using the Crystal Oscillator?

By GitHub stars, Tomu, I'm by theacodes, with 1,143 stars.

Can I simulate one of these boards using the Crystal Oscillator before building it?

Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
