Phase-locked loop (PLL) circuits exist in a wide variety of high frequency applications, from simple clock clean-up circuits, to local oscillators (LOs) for high performance radio communication links, and ultrafast switching frequency synthesizers in vector network analyzers (VNA). This article explains some of the building … See more In its most basic configuration, a phase-locked loop compares the phase of a reference signal (FREF) to the phase of an adjustable feedback … See more The phase frequency detector in Figure 3 compares the input to FREF at +IN and the feedback signal at –IN. It uses two D-type flip flops with a delay element. One Q output enables a … See more For narrow-band applications, the channel spacing is narrow (typically <5 MHz) and the feedback counter, N, is high. Gaining high N values with a small circuit is achieved by the use … See more To generate a range of higher frequencies, a VCO is used, which tunes over a wider range than a VCXO.
