Suggest me ICs for a frequency modulation synthesizer

FM monolithic IC??

Hi guys,
I am looking to build a frequency modulation synthesizer and was wondering if anything could suggest any IC for doing this?

What I would like to do is actually to use this as a pitch shifter eg. input an audio signal from one end and a frequency of 2 hz, 4 hz etc... on the other in order to shift up the frequency.

I have found signal generator chip such as the Max038 and the XR2206, does anyone have experience with these chips, thoughts?

Are there any other alternatives besides these?

Thanks!

From Maxim you can get free samples, but I would go for EXAR. They have more experience designing function generators.
I don’t have idea about other function generators, at these low prices.

Hello

You can go for MAX038, its a good choice also.
