100ns trigger pulses

[JR1]

Hello team,

which of the STM32 microcontroller is able to generate single trigger pulses in steps of 100ns +/- 10ns?

Most?

The TIM's have a one shot modes with granularity / resolution dictated by the APB clock they are attached too

[JR1]

An what is the maximum frequency of the APB clock?

How precise is the frequency (jitter) of the APB PLL?

See the DS / RM for the MCU in question.

Depending on the MCU/APB up to 200 MHz

They are all synchronous, the MCU expects a 50/50 duty, you can quantify the clocks via the PA8/MCO pin
