Dear forum..
I've been theorizing lately in my head about high frequency PWM.. like say, 5ns per step, 1024 steps per PWM cycle.. and the economics to generate a lot of these signals, with independent duty%.
Do you guys know of any ICs that could do this comfortably? I've tried to go with FPGAs but my Verilog is really bad and I managed to make a PWM on 32 signals but it takes about 105k gates with a simple i2c-like protocol to set the duty cycles. So I'm thinking there has to be something cheaper... I've seen some LED drivers that do PWM, but I'm not sure about that.
So if you could offer any hints, suggestions, I'd really be thankful!
Cheers,
B.
