Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers are integrated circuits which are widely used in the manufacture of electronic appliances. Indeed, these circuits are particularly practical and cost-effective when applied to embedded systems and real-time applications. The 843003AGI-01LF is a phase-locked loop (PLL) frequency synthesizer which provides a range of frequency synthesis options while offering robust performance and low power consumption. This device is therefore suitable for a variety of specific applications, primarily within embedded systems.

Embedded systems and real-time applications typically require rapid response to operating conditions, and the 843003AGI-01LF—with its cycle by cycle phase-locked loop control—ensures this. The device enables adjustment of the frequency, phase and duty cycle, meaning that it is especially suitable for systems which require onboard-based frequency-hopping for application specific communication systems. This makes it particularly useful for designing high-performance WiFi or Bluetooth systems.

In addition to its application in embedded systems, the 843003AGI-01LF can be used in telecommunications or the medical field. It is ideal for applications such as remotes, cellular phones, medical pieces of equipment and automation controllers. Historical telecommunications systems typically relied on frequency division multiplexing for dividing audio, data and other signals across a specific frequency range. The 843003AGI-01LF can be used to precisely control the frequency synthesis of frequencies viable for FDM signals, so this device can also be utilised in these systems too.

Beyond its application in telecommunication and embedded systems, this frequency synthesizer can also be used in the medical field. Medical pieces of equipment such as pacemakers require precise metal control to ensure accurate regulation of the patient heart functions. This frequency synthesizer device allows the metal to be designed precisely, so that it is within the necessary tolerance range.

The 843003AGI-01LF is a low power frequency synthesizer which features a wide range of adjustable parameters. An adjustable voltage-controlled oscillator frequency (VCOF) allows for a frequency range between 2.4GHz to 43GHz and grants a high resolution of frequency adjustment. The device also features programmable frequency dividers and an internal reference clock input.

The working principle of the 843003AGI-01LF frequency synthesizer is relatively simple. The device consists of two main components: a reference oscillator and a phase-locked loop. The reference oscillator provides an input frequency of fixed magnitude, while the PLL locks onto this frequency and generates outputs at a selected frequency ratio to the input. This device also has an active filter which helps to reduce the amount of jitter present in the system.

The 843003AGI-01LF can be used in a variety of applications such as embedded systems,Telecommunications and the medical field. This low power, high performance frequency synthesizer is suitable for applications which require frequency-hopping or highly precise metal control. The device features a wide range of adjustable parameters, thus allowing for precise frequency tuning and a low-power easy solution.
