The Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers are some of the most widely used types of components available in today\'s markets. The CDC2509APWRG4 is no exception and is an excellent choice for a variety of application fields. The CDC2509APWRG4 is a complete Phase Locked Loop (PLL) solution that includes a voltage controlled oscillator, a frequency synthesizer with frequency modulation, a voltage regulator and an output buffer. It is designed for frequency synthesis in a variety of communications, industrial, and consumer applications.

The CDC2509APWRG4 is useful for applications such as GSM/EDGE base stations, W-CDMA/TD-SCDMA/PDC/HSDPA/HSUPA lDM/PCS systems, satellite receivers, cellular modems, VHF receivers and military radios. The CDC2509APWRG4 is particularly well-suited to low power applications such as cellular base stations, where it can reduce system power consumption and increase the battery life of associated wireless devices.

The CDC2509APWRG4 offers several features that make it suitable for a variety of applications. The PLL consists of a voltage controlled oscillator (VCO) and a voltage regulator. The output of the VCO is coupled to the voltage regulator, which compensates for variations in supply and load voltages, thus maintaining the VCO frequency and phase accuracy. The frequency synthesizer with frequency modulation (FM) and phase modulation (PM) provides high accuracy frequency variability with low-noise jitter. The output buffer provides a constant output frequency with good linearity and low drift.

The working principle of the CDC2509APWRG4 is based on the use of a voltage controlled oscillator (VCO) and a frequency synthesizer. The frequency synthesizer can be programmed to generate a range of output frequencies with a minimum of jitter and noise. The VCO outputs a signal which is fed to the voltage regulator. The regulator detects variations in supply and load voltages and adjusts its output to compensate, thus maintaining the accuracy of both the frequency and phase of the VCO output. The output of the voltage regulator is fed back to the output buffer which provides a constant frequency output with desirable linearity and low drift.

The combination of the VCO, voltage regulator and frequency synthesizer allows the CDC2509APWRG4 to provide a highly accurate, stable and low power solution for frequency synthesis in a variety of applications. It is also capable of providing low jitter, accurate frequency modulation and phase modulation, making it ideal for applications such as WCDMA/TD-SCDMA/PDC/HSDPA/HSUPA 3G and 4G systems.

The CDC2509APWRG4 offers outstanding low noise and low jitter performance, making it the ideal choice for applications requiring high accuracy, low power, and low noise. The combination of the VCO, voltage regulator and frequency synthesizer provide a highly accurate, stable and low power solution for frequency synthesis, allowing for greater reliability and longer battery life in wireless applications.
