The 650R-01LFT is a type of clock/timing product designed to manage clock signals in applications like telecommunications, broadcast, computer, and network systems. It is a fully integrated, Frequency Synthesizer based on a patented synthesizer architecture which combines low jitter performance and wide tuning range with reliability and miniaturization. It contains a multi-phase PLL circuit along with temperature compensating logic, allowing it to generate reliable clocks in a wide range of applications.

The 650R-01LFT is a wideband Frequency Synthesizer, providing frequencies from 4kHz to 500MHz. It is compact, measuring only 15x15x8.5mm, and is an ideal choice for applications where size and speed are both critical. It provides a low jitter of 1ps rms and a low phase noise of -112dBc/Hz @126MHz. This combination of features and capabilities makes it ideal for use in applications where precise control over clock frequency and phase jitter is required, such as in broadcast and telecommunications systems.

At the heart of the 650R-01LFT is the PLL circuit, a highly integrated component that provided the overall clock signal control. The PLL circuit uses an integrated phase-locked loop, along with a temperature compensating logic circuit and a voltage controlled oscillator (VCO), to generate a reliable clock output with a wide range of frequencies. The VCO is controlled by an internal low-noise charge pump, which works together with the temperature compensating logic circuit to provide a wide tuning range while maintaining low jitter performance.

In addition to its outstanding performance in terms of jitter and phase noise, the 650R-01LFT has several features that make it suitable for a wide range of applications. It has an integrated spread spectrum input clock output, which can be used to help reduce EMI in noisy environments. It also has a programmable spread spectrum output, allowing for precise control over the spread spectrum frequency. Finally, it has an output duty cycle of 45/55, which can help reduce the need for additional duty cycle correction.

Overall, the 650R-01LFT is an extremely capable Frequency Synthesizer that can be used to generate reliable clock signals in a wide range of applications. It has a wide tuning range and low jitter performance, along with features to reduce EMI and improve duty cycle. With its compact size, excellent performance, and wide capability, the 650R-01LFT is an excellent choice for applications requiring precise control over clock frequency and phase jitter.
