Its compact size is perfect for use in dense electronic systems, where component space is limited. The oscillator also offers excellent noise performance, low power consumption and a wide operating temperature range.The 353SB3A307R oscillator operates on a 3V to 5V power supply and has a low start-up current of approximately 200uA. The device offers a low-phase noise of -171 dBc/Hz (max) and a low-amplitude noise of -142 dBc/Hz (max). It also has an extremely low power consumption of just 4.7mA at 3 Voltages and 6.5mA at 5 Voltages.The oscillator works by converting an external input signal and a crystal into an oscillating signal of the desired frequency. The crystal is a precise frequency controlling element, which helps stabilize the output signal to a pre-set frequency. The converted signal is then fed to an amplifier, which increases the amplitude of the signal and is usually filtered to reduce noise. This amplified signal is then sent to the output stage, which modulates the signal to the desired frequency or voltage.In conclusion, the 353SB3A307R oscillator is a reliable and cost-effective solution for applications requiring low-power, low-noise performance. It offers an extremely wide frequency range, robust noise performance, low power consumption, and a compact size.
