Anyone know of a source for a computer controlled vfo?

Control via serial port to ex. Yeasu,Icom - remote control protocol.

I would like to update my old analog vfo to computer controlled vfo.

Remote vfo control to 4,9 - 5,5 Mhz.

Two options:

Use a DDS chip like the AD9850 controlled by an MCU with a serial interface.

Use a PLL synthesiser controlled by an MCU with a serial interface.
