1)
With sourcing outputs, it must be taken into consideration that falling edges can be delayed as compared to rising edges
depending on the load. The on-load factor can therefore be falsified. Consider using a high-speed output if the load at
the output is greater than 240 Ω.
2)
The frequency has a basic accuracy of ±100 ppm with a resolution of 0.3638 mHz.
3)
Standard outputs are affected by jitter during generation of frequencies. The set period duration is not adhered to in
every period, but it is adhered to on average over several periods.
