653L20003I2T belongs to oscillators, which are widely used in numerous applications and involve a wide variety of working principles. Specifically, 653L20003I2T is a wideband frequency-hopping synthesizer that operates from 10MHz to 3GHz. Since it is a frequency-based type, the frequency hopping concept is adopted from the much older direct-conversion receivers. Due to its low phase noise performance, this oscillator can be used in radio communications, signal processing, test and measurement instrumentation, and other applications where radio frequency stability and accuracy are paramount.

The 653L20003I2T includes a low noise voltage-controlled oscillator (VCO) and a divide-by-N frequency divider. The VCO in 653L20003I2T operates from 500 MHz to 3GHz with a specified linear tuning range of + 15 MHz. It has a voltage-controlled input that allows the frequency range to be extended by up to ±100MHz. The VCO also has a high-Q resonator that manufacturers exploit to produce a very low phase noise.

The frequency divider in 653L20003I2T accepts the VCO output frequency and divide-by-N it. As a result, the locked frequency is accurately divided using a 1/N divider circuit. In addition, the divider allows the same signal to be used for multiple frequencies. This enables the 653L20003I2T oscillator to be locked to different frequencies simultaneously. By using this feature, the frequency of the oscillator can easily hop from one frequency to another without any external control, thus allowing the user to switch from one frequency to another as desired.

In conclusion, the 653L20003I2T is a wideband frequency-hopping synthesis oscillator that operates from 10MHz to 3GHz. It incorporates a VCO and a divide-by-N frequency divider to achieve low phase noise performance and frequency hopping capability. This makes the oscillator suitable for radio communications, signal processing, test and measurement instrumentation, and other applications where radio frequency stability and accuracy are paramount.
