What is the typical & maximum clock frequency for XY2-100?

XY2-100 typically operates at 2.0 MHz clock rate. This is due to the typical 100 kHz frame rate, with 20 bits being transmitted per frame, hence 20\cdot{}100 \text{kHz} = 2.0 \text{MHz}.

The maximum clock frequency is rarely specified but Raylase lists it as 10 MHz.
