The SI5350A-B02845-GTR is an excellent clock generator, PLL and frequency synthesizer, used in high-speed digital applications. It is based on SiTime\'s Super-Crystal Synthesizer technology that combines advanced high-frequency PLLs with crystal-based RF synthesis for applications requiring a perfect blend of performance and power consumption. The device is used in applications such as wirless communications, optical networking and communication infrastructure equipment.

The SiTime SI5350A-B02845-GTR consists of an integrated voltage controlled oscillator (VCO) and two phase-locked loops (PLL), both of which contain an internal reference oscillator. The VCO is used to generate a range of frequencies from 10 to 1000MHz. The PLLs are used to generate precise clock frequencies from 12KHz to 20GHz. The device also includes a set of on-board programmable settings that allow the user to customize the output frequency and the phase noise performance of the device.

The working principle of the SI5350A-B02845- GTR is based on the phase-locked loop (PLL). The PLL uses feedback to ensure that the phase difference between the output of the phase-locking system grows as the output frequency approaches and locks to the reference frequency. The PLL also includes a voltage-controlled oscillator (VCO) to generate the desired frequency, and a phase detection circuit to compare the actual output frequency with the reference frequency. When the phase difference between the two exceeds a certain threshold, the phase detector generates a correction signal that is sent to the VCO to adjust the output frequency. This process continues until the phase difference reaches the desired value, and the device is considered successfully locked at the desired frequency.

The SI5350A-B02845- GTR is also designed for low power consumption, as the device is able to operate on 3 to 5 volt supply voltages in active, power-down and power-saving states. It also features ultra-low jitter and phase noise performance, with typical phase noise measurements of -150 dBc/Hz at 1GHz and -175 dBc/Hz at 10GHz. The device was designed to meet the most stringent requirements of networking and communications applications and is fully compliant with the industry standards of IEEE 1553, JEDEC, PCI and other major standards.

Overall, the SI5350A-B02845-GTR is an excellent choice for clock generator, PLL and frequency synthesizer applications. It offers an impressive range of frequency outputs, combined with low power and low jitter, making it an ideal choice for a wide range of applications in the wireless communications, optical networking and communication infrastructure equipment markets.
