A Microcontroller-Based Phase-Locked Loop

Posted December 28, 2011 by Chris

“So here is the strategy: for a Softrock-class radio, we will use a phase-locked loop (PLL) that tunes using a resolution of 8kHz, say, and which might lock onto the frequency a little slowly. We will do this by dividing a crystal oscillator down to 8kHz, dividing a variable frequency oscillator by some integer so that it produces 8kHz when tuned to a desired frequency, and lock them.”
