The SI5335A-B09066-GMR is a high performance mulitlink frequency synthesizer mainly used in field application and its working principles. It features low jitter, wide operating temperature range, commonly used distribution clock interface and flexible options.

The SI5335A-B09066-GMR is capable of providing up to 25 low jitter, low phase noise clock outputs, supporting mulitlink clock distribution. The device offers frequently used outputs such as LVCMOS andLVDS, respectively, along with configurable support for HCSL, SSTL and HSTL technologies. It also supports 28-bit configuration of low phase noise PLL option. The device offers wide operating temperature range of -40 to +105°C, ideal for different application fields.

When it comes to the working principle of SI5335A-B09066-GMR, the device uses clock multiplication and phase interpolation in order to generate various clock frequencies. It consists of two Phase-Locked Loops (PLLs) connected in cascade with a phase interpolator, a clock divider, a divider fine tune (DFT) and a power sequencer. The PLL in the device locks on to the reference clock frequency and generates a phase locked loop (PLL) of desired frequency.

The second PLL in the device then locks the synthesizer to a reference frequency and multiplies the divided reference frequency by integer ratio, thus resulting in a frequency of desired output. This is then fed to the phase interpolator to obtain required frequency output. DFT allows the user to set clock divider in order to generate different types of output frequencies. This is then fed to PLL to tune the output range.

The power sequencer in the SI5335A-B09066-GMR helps in providing the clock signals at the desired output. It enables each of the outputs to power up one at a time and thus, initiate their independent functions on the system. The power sequencer also offers multiple levels of power sequencing, which helps in preventing internal glitches due to simultaneous power up of the device.

In conclusion, the SI5335A-B09066-GMR is an ideal device for clock and timing applications. It has been designed especially for mission critical applications and high performance computing, where jitter and phase noise are critical for high performance communication interface and reliability.
