Whether it is a communication module for high-speed data transmission or a control unit that requires extremely high clock accuracy, SG-8201CG can provide precise frequency support.

2.Frequency tolerance: Within the temperature range of -40 ℃ to+105 ℃, the frequency tolerance is only ± 15 × 10 ⁻⁶; The frequency tolerance is ± 25 × 10 ⁻⁶ between -40 ℃ and+125 ℃. This means that even in extreme temperature environments, SG-8201CG can still maintain highly stable frequency output, ensuring the reliable operation of automotive electronic systems. Whether in the cold northern winter or the hot southern summer, the vehicle can always maintain stable performance.

3.Phase jitter: The phase jitter is as low as 1.1ps (at a frequency of 125MHz and an offset frequency of 12kHz to 20MHz). Extremely low phase jitter can provide accurate clock signals for automotive electronic systems, which is crucial for ensuring the accuracy and real-time performance of data transmission. In high-speed vehicles, the SG-8201CG can ensure the accurate transmission of signals and bring smooth experience to drivers and passengers, whether it is the real-time perception of the auto drive system or the HD audio and video playback of the on-board entertainment system.

4.Power supply voltage: The power supply voltage range is 1.62V to 3.63V, which can perfectly match the power supply of automotive electronic systems, ensuring stable operation of the crystal oscillator in different power environments. Meanwhile, the design of low voltage also helps to reduce the energy consumption of automotive electronic systems and improve the energy utilization efficiency of vehicles.

5.Working temperature: The working temperature range can reach -40 ℃ to+125 ℃, which enables SG-8201CG to adapt to the complex temperature environment inside the car. Whether in the high-temperature environment of the engine compartment or the low-temperature environment inside the vehicle, SG-8201CG can maintain stable performance and provide reliable clock signals for automotive electronic systems.

6.Package size: Adopting a miniaturized 2.5mm x 2.0mm x 0.74mm package not only saves space for automotive electronic systems, but also improves system integration. With the increasing trend of miniaturization and intelligence in automotive electronic devices, the small packaging advantage of SG-8201CG is particularly prominent, which can meet the requirements of automotive manufacturers for space utilization and equipment lightweighting.
