LE87220KQC

The LE87220KQC is an interface designed for digital communication and specifically is tailored towards Digital Subscriber Line (DSL) technology. Human-computer interfaces and home automation devices, as well as new services such as IPTV have a high demand for high speed data transmissions and the LE87220KQC is well suited to meet the requirements. The device enables greater transmission efficiency in the network through its high speed Ethernet interfaces, and is configured to fit the applications it is required for.

The LE87220KQC is categorized as a line/mid-span modem according to the ITU-T G.993.2 standard, and is primarily intended for the fixed-network access and remote Internet Protocol applications. Its working principle is based on fast Fourier transform (FFT), and Dynamic Channel Allocation (DCA) techniques. Both of these techniques enhance the capability of broadband signals to cope with fading channels and other sources of signal degradation that arise. Specifically, FFT is used to transform signals into frequency-domain signals, while DCA modifies the necessary bandwidth to give the optimal signal transmission rate.

The device also offers advanced QAM encoding/decoding to make sure that data transmission is reliable and efficient in a wide range of networks. The frequency range of this device is up to 2.2 MHz, and it is capable of up to data transmission of 24 Mbits/s in downstream transmission, and up to 12 Mbps in upstream transmission. In addition, it has a data compression rate of up to 8:1.

LE87220KQC\'s applications vary from home offices, to video(IPTV) broadcasting, to telephony. This includes supporting any types of DSL-Tester, Home Automation Systems (home security management, thermal control, energy management, and so on). The device is also suited for online gaming (such as gaming consoles and gaming clients) and VoIP applications due to its data compression capabilities. This can significantly increase the speed of transmission, and make long distance communication more accessible. In short, this is a multifunctional modem that can be used in a variety of applications.

LE87220KQC enables the efficient and reliable use of broadband technology for the digital communication industry. This is accomplished through the adoption of Fast Fourier transform and Dynamic Channel Allocation technologies. The device’s frequency range ranges up to 2.2 MHz, with data transmission speeds of up to 24 Mbps in the downstream and 12 Mbps in the upstream. It has a data compression rate of up to 8:1 and has been used in multiple applications, such as IPTV broadcasting, telephony, gaming, and home automation. Thus, it is a powerful modem that provides efficient and reliable digital communication in a wide range of applications.
