FSK demodulation

I am new here, and maybe the topics may have been discussed already. If so show me how to find them.

I am extract FSK code embedded in 10.7 MHz. Freq shift is about 370 KHz. Data rate is about 700 BPS. Do anyone knows ICs which extract the base band data? There used to be several ICs which did this sort of job. However, most of them appear to be obsolete and not available now.

Could anyone offer any help?

The circuits and concepts are similar to those for FM detection via discriminator. Also, lots of useful information on FSK in ARRL archives.
