An alternate processor for tms320f2812

Question

Hello

I'm doing a PWM based project which requires the generation of 100 kHz reference wave and 400 kHz carrier wave.

I was told to use a DSP TMS320F2812 for this.

Due to the high price of the processor mentioned above, I'm looking for an alternative to fulfill my project requirement at a lesser price.

Can someone pls help me out?

Thanks in advance

There are specialized DDS frequency generators that will do this, or any other waveform that can be programmed.

That may be cheaper than using a DSP. For example, the AD9831 is less than $7. You can probably get samples.
