QuadFALC
®
Four-channel E1/T1/J1 Framer and Line
Interface Component
PEF 22554
The QuadFALC® is an addition to Infineon's market leading FALC®
family of advanced E1/T1/J1 Framer And Line Interface Unit (LIU)
components. As a four port E1/T1/J1 framer and line interface unit
(LIU),QuadFALC is optimized for a range of network equipment including
Radio network Controllers, Node B line cards, PBX or SDH/SONET ADMs.
The QuadFALC features a unique clock generation unit that accepts
any reference clock between 1.02 andd 20 MHz as well as integrated
analog switches for impedance matching or protection switching. Using
industry leading QuadFALC Evaluation support tools, system developers
can shorten design cycles while creating a wide range of highly flexible, low
BOM E1/T1/J1 line cards.
