  • Using the PC2 in-phase comparator output, the circuit in Fig 1 keeps the unlocked, or free-run, frequency of a 74HC4046 PLL near the locked frequency. With no signal input, the VCO output normally adjusts to its lowest frequency (one-half the locked frequency, f 0). In some applications, such a large frequency excursion may be undesirable.

  • The top trace is 10uS/div, and shows a rise time of about 25uS (it’s 60uS with the clock cranked up to 25kHz). Annoyingly, it has that characteristic LM358 style crossover mess. AND it only gets up to about 4v. The rise time is really what matters though, and it is orders of magnitude slower than the 74hc4046.
  • Phase Locked Loop (PLL) is one of the vital blocks in linear systems. It is useful in communication systems such as radars, satellites, FMs, etc. This chapter discusses about the block diagram of PLL and IC 565 in detail. The output of a phase detector is applied as an input of active low pass ...

  • The input data is a sine wave of frequency 4 Hz and amplitude 1 V. The frequency deviation is set to 50 Hz. The Modulated Signal scope illustrates that the frequency of the modulator output, Mod Sig, varies with the amplitude of the input data.
  • You get more than your 3 decade range. From the app note you don't have to change filter components, but I will say that such a circuit is noise sensitive, i.e. PSU and layout sensitive, don't expect it to work on one of those plug in boards. Decouple all your IC's and provide solid supply traces.

  • Here, eight capacitors are switched to ground in synchronism with the power line, making this circuit an eight-path filter. A power line sample obtained from transformer T1 and coupled through R8 and C14 is fed to a 74HC4046 phase-locked loop (PLL). A PLL consists of a phase comparator, a loop filter, and a voltage-controlled oscillator.

Lowering sq5I want to start using STM32 MCU in order to synchronize a multiple output power supply with a single frequency. So far I have used an analog PLL (74HC4046) for this purpose: The relevant range is 200-500 kHz. If the external freq. is out of range or doesn't exist the internal 400 kHz clock will distribute to all module. First of all, is it ... 74HC4046: 部品情報 Phase ...

  • Note that this circuit shows no obvious path for op-amp dc bias current. This is true if we assume that all elements are ideal or close to ideal. However, the imperfections in the electrode anodiza- tion, as well as in the dielectric separations and circuit board, provide sufficient paths for the very weak dc bias required by the TL082 op-amp. 74HC4046/74HCT9046A/CD4046 Phase-Locked Loop - Voltage Controlled Oscillator Frequency Online Calculator ...
