I am selecting an MCU (EFM8BB10F2G-A-QFN20 Datasheet here) for one of my projects and I found a strange thing. This MCU has only pin for external clock source:
Till now, I have never encountered this case. In every other MCU I have used, there were two pins for connecting an external crystal. How can I use a crystal in this case?

You can't (directly). The datasheet clearly states on the first page:
What you can use is a crystal oscillator (ie. crystal + active circuitry in the same component).
