Hot-selling and scarce PEB2255HV1.3 E1/T1/J1 Framer and Line Interface Component for Long and Short Haul Applications QFP

Product Descriptions

The FALC®-LH framer and line interface component is designed to fulfill all required interfacing between an analog E1/T1/J1 line and the digital PCM system highway, H.100 or H-MVIP bus for world market telecommunication systems.

Due to its multitude of implemented functions, it fits to a wide range of networking applications and fulfills the according international standards. The FALC®-LH offers a generic E1/T1/J1 analog line interface without the need to change external components. Optional crystal-less jitter attenuation reduces the amount of required external components.

Equipped with a flexible microprocessor interface, it connects to any control processor environment. A standard boundary scan interface is provided to support board level testing. Flat pack device packaging, small number of external components and low power consumption lead to reduced overall system costs.

Other members of the FALC® family are the FALC®54 for short haul applications, the FALC®56 for long haul and short haul applications as well as the QuadFALCTM supplying four long haul and short haul interfaces on one single chip.
