Resolution of PWM in F2812 - naay...@gmail.com - Feb 10 18:50:41 2008



Hi,

I would like to know the resolution of PWM generated by TMS320F2812. I am new to DSP, learning
things gradually. Can any of you answer me?

Thanks in advance.

Re: Resolution of PWM in F2812 - naay...@gmail.com - Feb 11 7:44:06 2008

Hi,
 
Thanks for your quick reply. If i calculate it comes around 17.8(is it in the unit of samples
per second?).
one more thing, If i look at the data manual of TMS320F2812, they mentioned the clock as
150Mhz, where as if i look at the eZdsp starter kit of TMS320F2812 features, it has 30Mhz
clock. Why there is a difference?. Which one of the clock to consider?  Because i have to go
for starter kit for my initial work. 
 
Another doubt is, DSP like TMS320F28044 has 150ps resolution in its output, i saw it in
datamanual. If i purchase the starter kit of F28044(with clock frequency 20Mhz)  will i get the
same resolution in its output?
 
I would also like to know whether this feature of 150ps PWM is available in TMS320F2812?  Sorry
to trouble you.
 
Thanks in advance
