The SI5350A-B04040-GT is a high performance, single-chip clock generator and frequency synthesizer from Silicon Labs. It integrates both a digital phase-locked loop (PLL) and a digital frequency synthesizer (DFS) and operates from a wide supply voltage of 1.8 V to 5.5 V. The device can generate up to 468 clock output frequencies up to 800 MHz, on either LVDS or CMOS outputs. The PLL supported output frequencies can go up to 800 MHz, the PLL frequency resolution is as low as 8 kHz, and the PLL jitter is 0.9 ps RMS across the supply voltage range.

The SI5350A-B04040-GT is designed with a Quartus II communication interface, which simplifies programming and configuration. It also features programmable input channel muxing and dynamic frequency switching, among other features. Additionally, it includes Silicon Labs’ SmartClock III™ technology for output synchronization, eliminating the need for external logic devices or special wiring. The device is also equipped with an integrated Phase Detector Interface (PDI), a temperature sensor, an SPI Bus Interface, and an on-chip voltage regulator.

The SI5350A-B04040-GT has a wide range of applications in the telecommunications, networking, and embedded industries. It can be used to time synchronize a variety of applications, including systems which require wireless communications, power line communications, embedded microprocessors, fiber optic transmission systems, and more. It is also ideal for products requiring high precision PLLs and DFSs in clock-generating and frequency synthesizing applications.

The clock generator works on a straightforward principle. The device receives an external reference clock and uses a phase-locked loop (PLL) to automatically adjust and synchronize the reference frequency to the internal clock oscillator. The PLL can be actively tuned using an internal VCO or an external VCO to achieve the desired frequency accuracy. The internal VCO can be adjusted to match the external oscillator frequency, and the PLL can then be tuned over a wide range, up to 800 MHz. The device also has a frequency synthesizer which can be used to generate additional clock outputs with frequencies different from the reference clock, depending on the internal oscillator frequency.

The SI5350A-B04040-GT is designed to be used in a wide variety of applications in the telecommunication, networking, and embedded industries. Its features, such as low jitter, wide operating range, programmable input channel muxing, dynamic frequency switching, and more, make it a perfect choice for frequency synthesizing and clock generating applications. The device\'s flexibility and adaptability make it an ideal choice for use in a variety of products.
