The working principle of the SIT8209AI-31-33E-133.333330X oscillator involves a capacitor (C1) and an inductor (L1) at its core. Initially a voltage is applied to C1, which causes it to charge up, while simultaneously causing current to build up in L1. When the capacitor is charged to its peak, the current flow is interrupted due to the polarity of the voltage applied to C1, and a voltage spike is generated due to the sudden discharge of L1. This voltage spike is sent to a transistor with a current inverter, resulting in an oscillating wave form.

The oscillator has an Output Enable Pin (OE) which allows the user to control the oscillation frequency and gain. The bias current can be adjusted as per the application requirements by changing the voltage level on the OE pin. It also has an internal voltage control loop which is used to adjust the gain of the transconductance element and control the overall operation.

The SIT8209AI-31-33E-133.333330X oscillator is a reliable, low-power and high-performance oscillator that can be used in a wide variety of applications. It has excellent performance and stability characteristics, making it an ideal choice for complex and demanding timing and synchronization applications.
