WebMost PLL models use a 25 MHz crystal. Only those based on RDA chips have a 27 MHz reference, which implies fractional PLL ratios to produce 9750 MHz and 10600 MHz. For a given output frequency, a fractional-N PLL can perform better than an integer-N PLL because it can use a higher reference frequency. But this is not what's being done in … http://www.pabr.org/radio/lnblineup/lnblineup.en.html
WebPLL that is capable of generating frequencies at integer multiples of the crystal reference. For example, using the PLL can provide up to an 8.2Mhz bus frequency while using a much lower cost 32 Khz crystal. An additional benefit of the PLL is reduced noise generation since high speed crystals and oscillators are not necessary.
WebApr 5, 2024 · A phase-locked loop (PLL) is a feedback circuit designed to allow one circuit board to synchronize the phase of its on board clock with an external timing signal.
