Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The 932SQL450BKLF is a digital clock generator and frequency synthesizer, suitable for a wide array of low jitter and low phase noise applications. It is a high accuracy component using a Phase Lock Loop (PLL) method to derive signals from a reference input. This component is designed for use in a wide range of applications such as home theater systems, cable or satellite receivers, or any other type of large-scale system that needs synchronization.

The 932SQL450BKLF is used to generate accurate clock frequencies from a crystal or clock source. This component combines the low power dissipation of high speed logic family with the low phase noise of advanced frequency synthesizer techniques. It contains a Phase Lock Loop (PLL) that is designed to use the most stable and reliable crystal oscillators or an external reference signal as its clock source. The component also contains a Voltage Controlled Oscillator (VCO), phase frequency detector, charge pump, dividers, and digital logic. This component also contains a power down reset switch and a guard ring which is added as a yield assurance feature.

The 932SQL450BKLF is ideal for low jitter and low phase noise applications. A reference input signal is used to generate an oscillator signal, which is then sent to the VCO. The frequency of the reference input is then compared to that of the oscillator signal and any discrepancies are corrected via the VCO and the phase frequency detector. The 932SQL450BKLF then uses the dividers to divide the output frequency of the VCO to the desired frequency. The guard ring feature helps ensure that the component is always in the correct state for optimum performance.

The 932SQL450BKLF works in two stages: the first stage is the PLL and the second stage is the dividers. The PLL is used to control the frequency of the oscillator. It constantly monitors reference input frequency with the VCO and corrects any discrepancies by adjusting the VCO. When the PLL has stabilised the reference input frequency, the dividers are used to divide the VCO output frequency to the desired frequency and then output the signal to the device.

The 932SQL450BKLF is a high-performance and highly accurate clock generator and frequency synthesizer. It operates at a very low jitter, guaranteeing a stable and reliable output for systems that require synchronization. This component offers excellent performance for a wide range of applications and is ideal for any system that needs to maintain strict synchronization. It is also suitable for applications such as timing and synchronizing digital video or audio data streams.
