Looking for some schematics of circuits that can decode MFM data stream to
binary.
Not looking for FDC chips.
Thanks.

What clock-speed will the signal have? Floppy is very slow,
2us clock. You can do that even in software with a fast
microcontroller. HDDs don't use MFM anymore, but for those
you need to streamline standard TTL, and may even need to go
to F or ALS families or thhe like use an FPGA.

The clock speed around 1mhz or 1us.
