Title: FM Transmitter w/ MC2833 IC
Post by illu5ionz on Feb 14^th, 2006, 2:36am

I'm designing a simple FM transmitter using the MC2833 chip. The datasheet for this IC can be found HERE

I've designed my own filter and audio amplifier. All i need to figure out is how to input my audio signal to the chip, use the Oscillator and FM modulator and then output the modulated signal to my own power amplifier to transmit via an antenna. Is there anyone who's familiar w/ this IC that can clearly explain or help me determine how to get started (i.e. set the frequency, how to wire it up to use the oscillator & modulator)? Or perhaps offer a URL where this is explained?

I've read the data sheet several times over but i'm new to this and i don't know where to start. Please help! Thanks in advance!!

Pin 3 is the "MODIN" input in. You can directly feed in your audio input without any coupling capacitors into this pin.
