The clock is driven by a microcontroller inside the keyboard, at a rate around 10-16.7 kHz. The data line is valid when the clock is low. Data and clock are open-collectors, so they can be connected directly to the computer with pullup resistors.

Webb24 sep. 2024 · Gaming keyboards were an area where until the last few years PS/2 was a feature for some users. The issue was that the Generic USB Keyboard driver could only report 5 simultaneous key presses (aka 5 Key Roll Over vs NKRO), PS/2 could do more (never saw a limit stated, might be indefinite if the keyboard was capable of supporting it).
