Hi guys My name is eddy and i needed some help regarding AD9851. Well i want to transmit FSK or MSK using this chip. The problem i face is that i cannot switch between the two frequencies. There is no frequecy select pin in this chip if anyone knows how to do this please tell me. I am also open to the idea of using a PIC but if it can be done without it that would be great. Regards, Eddy

Lift up that chip and drive an Analog Devices AD9953 under it. Then use the PS0 and PS1 pins, get up to four FSK frequencies.

Why not using a more sophisticated DDS chip, an AD9854 for example ? Yours,
