Oscillators

The 633V12503C2T is an oscillator designed for use in modern communication systems. It is part of a family of integrated circuit (IC) based oscillators developed by the company Microtime Corporation. These ICs provide a range of frequency control and other features which make them well suited for use in a wide variety of communications applications such as digital signal processing (DSP), frequency synthesis, and high-speed data transmission.

Application Field

The 633V12503C2T is a precision voltage controlled crystal oscillator (VCXO) with excellent phase noise and jitter performance. It is designed for use in a wide range of communications applications such as satellite communication systems, cellular base stations, DSL/broadband access, cable modems, and WiMax base stations. It is also used in military communications systems as well as in medical imaging and instrument control systems.

Working Principle

The oscillator is based on a quartz resonator which is the base element of the frequency control system. The resonator provides a stable and precise timing reference for the oscillator. The vibrational frequencies of the quartz resonator are tuned with an internal voltage-controlled amplifier (VCA). This internal VCA is then used to adjust the frequency of the oscillator. The 633V12503C2T has an operating range of 0.5 to 220 MHz with a tuning range of +/- 3ppm, allowing for precise frequency control.

The oscillator also features a selectable output voltage range of 2.5V to 3.3V. The 633V12503C2T has an integrated temperature compensation circuit which maintains operating frequency stability over temperature. It also features low phase noise and jitter performance, making it an ideal choice for applications requiring precision frequency control.

The oscillator is available in several packages, including DIP, LCC, and QFN. It is also compatible with surface mount technology for easy integration. With its high frequency stability, superior phase noise and jitter performance, and integrated temperature compensation, the 633V12503C2T is an excellent choice for applications requiring precise frequency control.
