LE88136BLC

LE88136BLC application field and working principle

The LE88136BLC is an integrated device designed for DSL/VDSL transmission and multipoint access applications. Designed by Lantiq, it is a single chip device that can be used in several different applications and can be easily integrated in various systems.

The LE88136BLC integrates all the necessary components for a DSL/VDSL system, including Line Interface Unit (LIU), main control processor, media access control (MAC), transmission control protocol (TCP) and carrier sense multiple access with collision detection (CSMA/CD). It also has a low power DSP for controlling data flow, a power management controller and a DC-DC buck switching regulator.

The device offers a wide range of hardware features such as symmetrical high speed data transmission, loop current detection and classification, line management, support for subrate pay, automatic rate adaptation and scalability, as well as power management and high power line sharing.

The LE88136BLC also features an extremely powerful software programmable engine with a highly configurable TCAM/AMP design, support for multiple digital-to-analog converters (DACs) and fully integrated transceivers. This enables it to support a variety of DSL/VDSL applications such as voice, video and data applications.

The working principle of the LE88136BLC is to provide a high speed transmission connection between multiple customers. It supports symmetrical data rates of up to 100 Mbps downstream and 20 Mbps upstream. Upon receipt of a data packet from the customer, the device computes the packet length and determines the maximum data rate for the connection. It also records and stores the customer\'s current throughput and updates it on every packet passage.

The LE88136BLC also performs line monitoring and maintenance, signal detection and classification, remote port control and data flow control. It provides performance metrics such as latency and throughput, and diagnostic features such as signal integrity test, signal power levels and static per port statistics. It also supports advanced features such as layer 3 routing, VLANs and multicast.

The LE88136BLC is ideal for use in DSL/VDSL applications, as it offers a low cost, low power, high performance solution that can be easily integrated into various systems. It is suitable for consumer and enterprise applications, as well as providing access to IPTV, VoIP and media streaming applications.
