NJM3359D application field and working principle

The NJM3359D is a Video Noise Reduction IC from NJRC, which has been widely used in the consumer and professional audio/video industry today. This single chip technology IC has helped significantly improved both the audio and video quality. Due to its successful integration and high level of performance, the NJM3359D has become an important component of almost any audio/video equipment.

The NJM3359D is designed to reduce noise levels present in audio and video signals. It does this by using an adaptive filter circuit, the operation of which is controlled by a microcomputer. By estimating the level of noise present, this filter will actively reduce the noise levels without affecting the signal integrity. The adaptive filter circuit also works to eliminate the "ringing” of the audio signals caused by the interference of the echoes in the signal.

In many applications, it is necessary to reduce the noise level in order to obtain higher quality audio or video signals. The NJM3359D is specifically designed for this purpose. It is capable of reducing the noise level by up to 75 dB in digital video signals and up to 60dB in digital audio signals. The signal-to-noise ratio is also improved significantly.

In addition to noise reduction, the NJM3359D also offers various features that help optimize the performance of the audio/video equipment. It has an integrated digital signal processor to improve the dynamic range of the audio/video signals. The digital signal processor also helps to reduce digital crosstalk and the source color distortion. It also offers a full range of video I/O functions which allows the user to switch between different video standards like PAL, NTSC or SECAM.

The NJM3359D also offers various advanced features such as a three-stage low-pass filter to improve the video signal-to-noise ratio and a tone control circuit to shape the audio signal. It also comes with an audio delay control circuit to optimize the sound delay in multi-channel systems.

The NJM3359D is ideal for any application where audio/video signal quality needs to be improved. It is an important component in the design of new audio/video equipment, as well as an easy way to upgrade older equipment for improved performance. It is also a cost-effective way of improving the audio/video signal quality, without adding any extra components to the circuit.
