Oscillators are circuits composed of certain components and configured with an oscillation frequency. In most cases, the oscillator circuit mainly comprises an amplifier, a filter, and a feedback. 636M3C020M00000 oscillators belong to a PLL based VXCO, which is designed for high frequency applications.

The 636M3C020M00000 oscillator is installed into an exclusive SMD package and is able to maximize cost-effectiveness and reliability for a variety of applications. It is mainly used inwidely deployed wireless applications such as Wi-Fi, WiMAX, ZigBee and Bluetooth, as well asother RF-enabled device communications.

The 636M3C020M00000 oscillator utilizes a Frequency Divide Down Technology that liberates the user from the need to decide on proper VCO and divider ratios when implementing a PLL frequency synthesizer. It allows a user to easily select a frequency source from within the VCO range and still obtain the desired frequency while also providing a variety of programmable frequency options.

The working principle of 636M3C020M00000 oscillator is based on the varactor diodes which utilize electric fields to change the capacity of a circuit’s capacitors. This change in circuit capacitance alters the resonant frequency at which the oscillator circuit can generate an output signal. The 636M3C020M00000 oscillator uses varactor diodes in its oscillator core, with output frequencies in the range of 16 MHz to 20 MHz.

The circuit’s active components include two transistors and a filter network. The feedback network includes a tuned inductor and variable capacitors. Its loop gain follows a bandpass response, meaning that the oscillator remains stable over gain variations. Frequency drift is kept at a low value through temperature compensation.

The primary purpose of the 636M3C020M00000 oscillator is to limit the component count and cost of the PLL, while maintaining a high level of reliability and performance. It offers a frequency range from 16 MHz to 20 MHz, low phase noise, fast start-up in cold and hot conditions, low phase noise and fast start-up characteristics, as well as a wide operating temperature range.
