The SI5338C-B08176-GMR is a high-performance frequency-synthesis clock device designed for applications that require good jitter performance and utmost frequency accuracy. This clock device is designed for applications such as clock distribution, circuit-board synchronization and interface communication. It is also suitable for telecommunication, military, aerospace and other high-performance applications.

The SI5338C-B08176-GMR provides a flexible, high-performance digital-control oscillator in a small package form. It features digital frequency synthesis, programmable spread spectrum, precise frequency adjustment over a wide range, low charge pump current, and programmable voltage control. The device is also capable of automatically adjusting its output frequency when the applied clock voltage changes. This ensures efficient clock control and improves the overall system jitter performance.

The working principle of the device is based upon the principle of phase-locked-loop (PLL) frequency synthesis. The device uses a combination of digital and analog components to produce a stable clock output, with precise frequency and timing accuracy. The clock device synthesizes the output frequency from a reference frequency, which is usually provided by an external crystal oscillator. A phase detector compares the reference frequency with the output frequency and produces an error voltage, which is then fed back to the device’s voltage-controlled oscillator (VCO). Any changes in the frequency of the VCO are fed back to the phase detector, allowing the loop to adjust the PLL output frequency until it is matched to the reference frequency.

The SI5338C-B08176-GMR is optimized for use in clock distribution and other applications that require precise timing and frequency accuracy. Its output is capable of operating at frequencies up to 200 MHz, with a maximum jitter of 200 fs. It also features a wide a variety of programmable features, such as register-programmable outputs, spread spectrum control and clock bandwidth. The device can be programmed over the I2C or SPI interface, allowing it to be remotely controlled.

In conclusion, the SI5338C-B08176-GMR is a high-performance frequency-synthesis clock device designed for applications that require good jitter performance and utmost frequency accuracy. It is suitable for applications such as clock distribution, circuit-board synchronization and interface communication. The device is based on the principle of phase-locked-loop frequency synthesis, and is capable of programmable frequency adjustment and clock bandwidth control. It is optimized for use in clock distribution and other applications that require precise timing and frequency accuracy.
