Need a microcontroller with a built in PLL capable to output the generated frequency

[mwmmboy]

Hi guys,
I need to find a microcontroller with a built in pll capable to output the generated frequency.
Otherwise a solution to generate with a microcontroller frequencies from 500Khz to 1.2 MHz.

Any suggestion?

PLL

Hi,

I know that Microchip will be coming out or already have with MCU that can make PWM at this freq. This PIC will be used to control power supply market, but they will also fit your needs.
see: www.microchip.com

Good luck.

Re: PLL

Tx, I have already used PIC for generating PWM, but I I need to generate 1.150 MHz, the PWM clock source is the clock divided by 4 and then there are other division in the Timenr register, so in my opinon it is noto possible to obtain any frequency...
This is the problem, my set o frequrencies I need it can not be obtained by division.

Any other suggestion?


Tx again

Re: PLL

Hi

You can use LPC21xx ARM controller can generate PWM at very high speed ,you can also use the DSP56F8xx from freescale who can genberate PWM into the mHz range

ALL the best
