EG-2121CA 266.0000M-PHPAB application field and working principle

Oscillators are electronic circuits that generate a repetitive signal without signal input. The field of oscillator application is diverse and includes communication applications, navigation systems, radio and television broadcasting, automatic control and electronic metering. The EG-2121CA 266.0000M-PHPAB is a voltage-controlled oscillator (VCO) designed with low-power, low-noise and high-stability operations in mind.

The EG-2121CA 266.0000M-PHPAB is composed of a voltage-controlled oscillator (VCO) and a charge pump drive circuit. The VCO is composed of a set of LC resonant circuits, and its frequency is determined by EIN (external input voltage). The charge pump is composed of two clock generators, M1 and M2, with one of them providing a clock to be used as the reference clock for the other. When an input voltage (which is provided to the charge pump) is applied, the frequency of either clock changes in response to it. The output frequency of the oscillator is determined by the differences between the two clocks.

The EG-2121CA 266.0000M-PHPAB is suitable for use in communication applications, such as wireless data transmission systems, and for GPS navigation systems. The VCO has a frequency range of 2.55MHZ to 2.8GHZ, with a maximum output power of 5.0dBm, while the charge pump features a low-noise variable frequency drive current. In addition, the VCO features excellent linearity and low-power operation.

The PPTC_EG-2121CA 266.0000M-PHPAB features a wide temperature range (– 25°C to + 70°C) and excellent stability, making it suitable for both indoor and outdoor applications. The module also has a power-on reset function, which ensures that the VCO is properly calibrated and working at the correct frequency.

The EG-2121CA 266.0000M-PHPAB is a highly reliable, low-cost, low-power, and high-stability voltage-controlled oscillator. Its wide frequency range, low-noise drive current, and wide temperature range make it suitable for a variety of applications, including communication and navigation systems.
