You may buy the module from ebay if just for hobby.

I see. You may have a look at this one from Silicon Labs:
https://www.silabs.com/products/audio-and-radio/fm-radios/si4702-03-radio-receivers

Or from NXP:
https://www.nxp.com/products/media-and-audio/am-fm-radio-audio:MC_71513

They are more professional chips. They are active. The price could be a problem for your application.

Or you may still buy the TEA5767 modules. It is widely available at ebay and aliexpress, 200 pcs should not be a problem.

What is an "FM Radio"?
a receiver? Analog output?
