Phase Lock Loops 101 with Bil Herd

in tutorials by DP | 1 comment

Robert let us know about another video tutorial on Phase Lock Loops in the comments of our previous post.

PLLs generate an output signal that is phase-synchronized to an input signal. They are widely used in telecommunication, radio, and computer systems. One place we commonly find PLLs is the frequency multiplier circuit inside microcontrollers. The PIC 18F2550 used in the IR Toy has one that multiplies a 20 MHz crystal input to 96 MHz needed for the USB module.

Thanks Robert! Via the comments.
