I need to have a pic emulate and communicate with an I2C
buss. The PIC controller would then talk to two RF Synthesizer chips and an
8 bit DAC.

The synthesizer chips have three wire control. The DAC could be
I2C or serial control.

Frequency control information would be sent over the I2C bus and
the DAC would set a voltage level.

The PIC would set the frequency and voltage level.

The PIC would command the Synthesizer chips to a frequency

The values could be programmed in flash memory so that
on power up it would come back to the same frequency.

Has anyone out there done anything like this before?

Any recommendations?
