Introduction
TM
The QuadLIU
is the latest addition to Infineon’s family of sophisticated E1/T1/J1 Line interface Components.
This monolithic four channel device is designed to fulfill all required interfacing between four analog E1/T1/J1 lines
and four digital framer interfaces for world market telecommunication systems.
The device is supplied in P/PG-LBGA-160-1 package (P/PG-LBGA-160-1 is RoHS compliant) and in a PG-TQFP-
144-17 package, and is designed to minimize the number of external components required, so reducing system
costs and board space.
Due to its multitude of implemented functions, it fits to a wide range of networking applications and fulfills the
according international standards.
Crystal-less jitter attenuation with only one master clock source reduces the amount of required external
components.
Equipped with a flexible microprocessor interface, a SCI and a SPI interface, it connects to various control
processor environment. A standard boundary scan interface is provided to support board level testing. LBGA
device packaging, minimum number of external components and low power consumption lead to reduced overall
system costs.
