ADF4007BCPZ-RL7

The ADF4007BCPZ-RL7 is a Phase-Locked Loop (PLL) equipped with active loop filter and Voltage Controlled Oscillator (VCO). It is designed to reduce jitters and improve phase noise performance in clock generation applications. This PLL is suitable for use in critical applications such as high-frequency clock synthesis, clock distribution, and data recovery.

The ADF4007BCPZ-RL7 operates in two modes: Static Frequency Synthesis Mode and Sweep Mode. Static Frequency Synthesis Mode is used to synthesize and generate a fixed frequency output with a single reference input. When in Sweep Mode, the PLL scans over a pre-programmed frequency range while maintaining low jitter operation. The reference and output frequencies, predefined settings, and output levels are all programmable and configurable.

At the core of the ADF4007BCPZ-RL7 is the Phase Frequency Detector (PFD) and Voltage Controlled Oscillator (VCO). The PFD is a comparison type circuit that compares the phase of reference and feedback signals and produces an output proportional to the phase difference. This output is fed to the Low Pass Filter (LPF) which then produces a voltage that is used to control the VCO that generates the desired output frequency.

The ADF4007BCPZ-RL7 also includes an active low pass filter (LPF) which reduces jitter and improves the signal-to-noise ratio of the output signal. The filter is designed to filter and reject undesirable frequencies present in the reference signal, thus creating a stable and low jitter output. The DC control signals can be adjusted to customize the filter characteristics.

This PLL can be used in applications such as high-frequency clock synthesis, clock distribution, and data recovery. It is also suitable for use in communication systems such as GSM, WLAN, and multiplexers. It is also used in RF receiver and timing circuits. The ADF4007BCPZ-RL7 is an ideal solution for applications requiring low jitter and high frequency stability.
