The SI5351A-B07681-GT is a Clock Generator and Programmable Spread Spectrum Clock Generator ideal for use in high speed digital designs such as wireless networks and digital broadcast applications. This device provides many features to improve signal integrity, reduce jitter and simplify design processes.

The application field of the SI5351A-B07681-GT is mainly related to Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers. This clock generator is designed to provide a wide range of output frequencies and multiple output formats from a single device, using standard clock and timing components in applications that require frequency synchronization such as:

• Network time servers
• Mobile base stations
• High speed digital video
• Wireless communication & Network infrastructure
• High-end personal computers & workstations
• Airport security systems
• RFID
• Satellite systems
• Data acquisition

The SI5351A-B07681-GT has a synchronous design architecture allowing multiple clock generators to be used to create single output products. It supports spread spectrum output, with frequency agility and low skew outputs, allowing a wide range of frequencies to be generated. The output frequencies can be programmed from 100 Hz up to 150 MHz, while the device can be configured to accept a low-frequency reference signal of 0.25 MHz, 1.544 MHz, or 2.4576 MHz.

The device includes a 32-bit phase accumulator, a programmable frequency divider and a programmable phase divider. The combination of these functions allows a flexible output frequency selection and clock signal timing control. The output frequency and power can also be adjusted using the Frequency Lock Loop (FLL) feature, which can prevent any changes in frequency due to environmental temperature changes or power fluctuations.

The SI5351A-B07681-GT has a wide range of features that enable the creation of a spread-spectrum clock signal. These features include the frequency modulation, frequency dithering and clock jitter attenuation. The frequency modulation feature allows the output frequency of the device to be adjusted over a wide range of frequencies with a minimal change in power. The frequency dithering feature allows an additional level of random frequency variation to be applied to the output signal, reducing the impact of interference and unwanted frequency responses. The clock jitter attenuation feature allows the user to configure the device to reduce the jitter on output clock signals, minimizing data transmission errors.

In summary, the SI5351A-B07681-GT is a highly integrated clock generator that offers a wide range of output frequencies and multiple output formats from a single device. It can be used in wireless communication, RFID, mobile base stations and high speed digital video applications to provide robust frequency synchronization, reduce jitter, improve signal integrity and simplify design processes.
