NJM2580D application field and working principle

The NJM2580D is an intelligent video amplifier module from New Japan Radio Corporation. It is a microcontroller-based amplifier module designed to enhance the clarity of video signals. It is capable of amplifying the input signal to a higher level and also providing superior signal-to-noise performance with low distortion. The device is suitable for both broadcast and professional video applications and can be used as an alternative to conventional amplifiers.

Application fields

The NJM2580D is mainly used in video applications such as CCTV cameras, broadcast television systems, multimedia display systems, and video production systems. It can also be used in professional applications such as video capture and recording applications, video editing, and video conferencing. It is also suitable for video applications requiring low noise, low distortion, and bandwidth up to 8 MHz. The device can be used for amplifying analog video signals and for providing superior signal-to-noise performance.

Working Principle

The NJM2580D is a three-input, four-output video amplifier module that utilizes a differential input architecture. The device is equipped with a number of powerful built-in features such as gain control, threshold control, frequency response compensation, and output filtering. In an application, the input signal is applied to the device, and it will adjust the gains of the three inputs to optimize the signal-to-noise performance. When the gain of an input is adjusted, the device also compensates for frequency response variations in the output signal. Additionally, the device features a compression circuit that operates in the analog domain, allowing it to maintain signal fidelity while providing sharp image details and accurate color reproduction. The output signal can then be filtered selectively to further reduce noise.

The NJM2580D also features a number of advanced signal processing technologies. These include proprietary Noise-Elimination Technology (NET) for reducing noise levels, Power-Saving Technology (PST) for reducing the power consumption of the amplifier, and Direct Control Technology (DCT) for enabling simpler control of the device. In addition, the device is equipped with an on-board audio amplifier that supports audio inputs and outputs. This enables the device to be used in applications such as AV production, video conferencing, and tutorials.
