Introduction

ISL43841IR is a family of high frequency, low distortion multiplexers, demultiplexers and analog switches. It is designed for applications where low noise and low power consumption are essential. This product family is especially suitable for use in systems requiring low pass and high pass filtering, or SCSI/SAS applications.

Application Field

ISL43841IR has many highly desirable features including excellent linearity, repeatability, and low power consumption. This device is ideal for applications such as audio routing, digital audio interface, SCSI/SAS data routing, spread spectrum antennas, and video clock switching. This multiplexer, demultiplexer and analog switch can also be used in HDTV, IPTV, CATV, and satellite TV.

Working Principle

ISL43841IR multiplexer and demultiplexer have a variable select function, allowing multiple inputs/outputs to be connected to a single line in order to parameters. The device is also capable of controlling multiple channels without utilizing Data Lanes. The analog switches incorporated within this product family are designed for low power consumption by using the gate biasing feature of the P-channel MOSFETs. By using a low amount of power, these analog switches can significantly reduce the amount of heat generated in the system, which improves signal integrity at high frequencies.The device also has two high-performance, fully differential signal amplifiers that are capable of providing low distortion and a wide signal range. This can provide excellent performance for multiplexing and demultiplexing audio, video, and digital signals. ISL43841IR also includes programmable gain that can be adjusted to match system requirements.

Conclusion

ISL43841IR is a family of high-frequency, low-distortion multiplexers, demultiplexers, and analog switches. It is ideal for applications such as audio routing, digital audio interface, SCSI/SAS data routing, spread spectrum antenna, and video clock switching. The device includes two high-performance, fully differential signal amplifiers that are capable of providing low distortion and a wide signal range with programmable gain. ISL43841IR is a great choice for applications where low noise and low power consumption are essential.
