Re: Can i make a very fast squarewave with peripherals ?
I have attached the 3102 datasheet , that is used in the example circuit from MN3207 datasheet
This clk generator has a low current capability and donýneed a serial resistor.
In the acese of pic pins output , they can give a lot of current, but max. allowed is 25mA
(as I remember at the moment)
So with a capacitive load (more than 50pf?), the current must be limited with a resistor intercalated in series.
220 Ohm with 5V in Vcc , gives a near 20mA limit
As it is not a DC load, may it be use a smaller resist., but it requires more study.
It is necesary to define if you need several diferent freq. or you will seep freq. in a continuous mode.
Respect of two complementary outputs, any HCMos inverter can do this with a very little delay
