Voltage-controlled oscillators (VCOs) are highly important components in many circuits that require signal generation or signal processing. The UMX-1797-D16-G is one example of such a component, which is a frequency programmable VCO that offers a wide range of signal frequencies and control methods. This article will discuss the application field and working principle of the UMX-1797-D16-G VCO.

The UMX-1797-D16-G VCO is a frequency programmable device that is capable of generating signal frequencies from 0.1 Hz to 1.5 GHz and with a frequency resolution of 12-bits (0.2 Hz). The general application field of this component is for frequency synthesis and tuning applications as well as for signal generators and signal processing circuits. It is also suitable for use in a wide range of industries such as communications, automotive, aerospace, and military systems.

The component has two control modes available: "Ramp" and "Direct". The "Ramp" mode is used for low-frequency synthesis, and in this mode, the VCO can reach a maximum frequency of 10 MHz. The "Direct" mode is used for high-frequency synthesis, and it is capable of reaching frequencies up to 1.5 GHz. To switch between the two modes, a low-voltage electronic control (LEV) signal is required.

The UMX-1797-D16-G VCO\'s working principle is based on the combination of an oscillator and a frequency divider. An oscillator takes a signal as input and produces an output signal with substantially higher frequency. The frequency divider is then used to convert the output signal back to its original frequency range. The frequency divider is programmable and can divide the output signal by any ratio up to 16. By varying the input signal, the ratio of the frequency divider, and the mode of operation, it is possible to generate any frequency from 0.1 Hz to 1.5 GHz.

The component requires a total of two power supplies for its operation. A supply voltage of 2.4V to 4.5V is required for the "Ramp" mode, and a supply voltage of 5.5V to 6.1V is required for the "Direct" mode. The power consumption of the UMX-1797-D16-G is 5 mW in the "Ramp" mode and 10 mW in the "Direct" mode.

The UMX-1797-D16-G is a highly versatile VCO, offering a wide range of features and options. Its wide frequency range and programmability make it suitable for a variety of applications. Its low power consumption also makes it an attractive choice for many types of circuits and systems, such as communications, automotive, aerospace, and military systems. It is an ideal solution for applications that require signal generation or signal processing.
