MSK modem chip
 

Can someone suggest a chip for a 2400 MSK modem (which is FSK at 2400
baud with the frequencies being 2400 and 1200 Hz). I'd like a simple
chip that is suitable for a radio application.


I'd like something simple, like the old (discontinued) MX614 chip.


Thanks,


Art

Thanks Travis,

It would be good, except the chip appears to be a 1200 baud modem.

I need a 2400 baud chip.

Sorry, didn't read closely enough. How about this one?
