Working Principle

The SIT9002AC-38H25SK oscillator consists of a programmable oscillator core, based on a quartz crystal, combined with a temperature-compensated clock circuit. The oscillator is designed to provide high accuracy, low jitter and stability over a wide temperature range. The performance of the oscillator is designed to meet tight requirement in applications such as those found in communications, networking and timing applications.

The oscillator core consists of a quartz crystal and an external oscillator circuit that can be configured for different frequencies and with selectable output frequencies. The crystal vibration is detected by an electrode and the frequency is converted to an electrical signal. The signal is then processed through the external oscillator and the output is trapped with a digital filter circuit to reduce jitter and provide a low noise output. A temperature compensation circuit is also used to provide temperature stability.

The SIT9002AC-38H25SK is designed for both standard and application specific applications, with features such as programmable frequency and temperature compensation, programmable output power and voltage, and selectable rise and fall times. It also supports an integrated temperature sensor, enabling the device to self-compensate for temperature changes.
