SI5351A-B03449-GT

The SI5351A-B03449-GT is a general-purpose clock generator and multi-output PLL-based frequency synthesizer device. It is part of the Clock/Timing group, with Clock Generators, PLLs, and Frequency Synthesizers being three of its main categories. The device control registers can be programmed through an I2C/2-wire digital interface.

The SI5351A-B03449-GT is used in a wide range of applications from consumer electronics to industrial and medical. It is an ideal solution for clock generation in digital systems such as watches, clocks, toys, digital audio and video devices, as well as for high speed clocking of microprocessors, DSPs, and FPGAs. In the industrial and medical fields, the device can be used for frequency control of analog and digital synthesizers, and for driving lighting, DSL, or communications systems.

The SI5351A-B03449-GT features a programmable output clock that can generate a frequency range of up to 2.88 GHz, and it provides 6 independently programmable outputs ranging from 0.1 to 200 MHz. The device employs a lookup table-based architecture that offers 15 output settings providing sinusoidal outputs with 0.1 Hz resolution. Each of the 6 outputs can be independently programmed to one of 4 settings. Programming is done through an I2C/2-wire digital interface.

The working principle of the SI5351A-B03449-GT revolves around its use of a multi-phase PLL, along with multiple banks of programmable output dividers and phase frequency detectors. The multi-phase PLL acts as the main clock timing source, which is then divided down to provide the output frequencies. The phase frequency detectors are used to check the phase and frequency of the output signals and adjust them accordingly. All of the settings and programming can be done using the I2C/2-wire digital interface.
