We want to connect Aduc 847 external clock via P 2.7
We want to use 500 MHz vco.
Can Aduc 847 handle this?
** We need 40 khz PWM signal with 16 bit control.
500MHz external clock on P2.7 is very high for ADuC847. I will recommend to use only around 12MHz range. And even if you used 500MHz, you won't be able to achieve 40kHz output rate with 16bits resolution.
Thanks for information.
So, do you have any suggesttion for me?
Which type card can we use for 40 kHz output rate and 16 bits resolution.
The way I see it, 40kHz of 16bit PWM is quite impossible for an MCU since you'll be needing a core clock at GHz speed. If you lower your PWM resolution to 8bit, you'll only need a 10MHz core clock which can be handled by most MCU.
