The FS7140-02G-XTD, part of the comprehensive Clock/Timing device family, is a high-performance frequency synthesizer designed to enable quick, accurate switching of frequency rates, without any combination of adjustable crystals or reference clocks. It provides high-speed clock synthesizer with very low jitter in the output frequency ranges, making it a suitable choice for applications such as router, switch, and firewall design. The FS7140-02G-XTD is a versatile, single-chip frequency synthesizer capable of generating frequencies ranging from 30MHz to 4.3GHz, in 1 Hz increments. The integrated PDLL allows for rapid, low-jitter switching between different frequency sources or bands, as well as providing one or two reference frequency sources.

The key feature of the FS7140-02G-XTD is its ability to synthesize frequencies that are not be achievable with traditional frequency synthesizers. By employing the integrated, high-speed PDLL, the FS7140-02G-XTD is capable of synthesizing and generating exact frequencies using only a single crystal reference clock with a very low jitter and high power-efficieny, which makes it an ideal choice for applications that require rapid frequency switching and the most accurate frequencies possible.

The FS7140-02G-XTD frequency synthesizer is ideal for applications that require a fast switching between frequency bands, as it has a fast switching time of less than 200ms. It also has frequency locking features and an integrated phase-lock loop (PLL) that can be used to rapidly switch between frequencies and different frequency sources, as well as providing a single reference clock for all frequency outputs.

The FS7140-02G-XTD is widely used in telecom, datacom and military communication systems, radar base station and navigation systems, and other related industries. Its low power requirements and wide bandwidth, high switching speeds, and low jitter enable the FS7140-02G-XTD to perform exceptionally in a variety of critical applications. The device can be used to provide high-speed clock synthesizers for such signals as PCM, SDH, SONET, TDM, and Gigabit Ethernet. It is also ideal for digital transmission systems, radio receivers, and digital systems requiring buffered signals or very low jitter.

In terms of working principle, the FS7140-02G-XTD frequency synthesizer relies on a phase-lock loop (PLL) system to generate clock signals that are output at the desired frequency. The synthesizer is optimized to perform a minimum number of reference clock input taps and low power noise floor, coupled with the use of a low jitter oscillator for tight frequency accuracy, enabling the device to achieve tight frequency accuracy at very low power requirements.

In addition, the FS7140-02G-XTD uses a Cross-Bar switch technology, allowing users to set up the device with any frequency combination. The device also features various output formats, including LVCMOS and LVDS, phase noise optimization, and frequency-settings over the serial control interface for remote configuration.

The FS7140-02G-XTD frequency synthesizer is one of the most advanced and reliable frequency synthesizers available today, and is an ideal choice for applications where quick switchover, low jitter and high accuracy are needed. It provides a complete solution that helps to maximize system performance and increase system flexibility, while simultaneously reducing design time, cost and complexity.
