82V2051EPP8 is a single-chip ADSL transceiver IC designed for multimode VDSL, HDSL, and ADSL applications up to 8 Mbps. It is designed to meet the requirements of the ANSI T1.413 Issue 2 and ITU G.992.1 standard. This IC is combined of five independent parts: Transmitter, Receiver, Digital Signal Processor (DSP), Digital Line Manger (DLM) and Advanced Timing Control (ATC).

82V2051EPP8 Application Field

The 82V2051EPP8 IC is used in the field of broadband communication, such as in the residential, business, and enterprise data, telephony and video communication systems. Furthermore, the IC can be used in applications related to the IP business data, such as multi-room television, multimedia over CATV, video on demand, video conferencing, and video searching. Because this IC is suitable for the FTTC (fiber to the customer) application, it is widely used in the broadband access network.

82V2051EPP8 Working Principle

The 82V2051EPP8 IC is composed of a DSP, powerful analog, and digital features with a flexible and configurable architecture. This provides the bridge between the customer premises and the digital subscriber line (DSL) service provider’s network. It works by first receiving the signals from the local exchange, which contains the data, voice, and video information. The receiver at customer premises then decodes the signals and separates the signals into their individual components. The transmitter then converts these signals into encoded and then transmits this encoded signal back to the local exchange.

The IC architecture allows for the complex process of synchronization, line management, as well as data and voice packet processing. The DSP is responsible for all signal processing and for the Analog/Digital conversion of signals received from the local exchange. The DLM is responsible for line maintenance and management. Finally, ATC is responsible for synchronization and timing of the transmitter and the receiver.

Conclusion

In conclusion, the 82V2051EPP8 IC is an integrated solution for single-chip ADSL transceiver applications and is suitable for FTTC applications. This IC is composed of five independent parts which form a powerful analog system, and which provide an efficient bridge between the customer premises and the DSL service provider’s network. This IC is a perfect fit for the applications related to IP business data, telephony and video communication.
