PEF2552EV1.1

Overview

The PEF2552EV1.1 is a telecommunications interface integrated circuit manufactured by Lantiq, belonging to the DualFALC series. It integrates two independent channels, each combining a framer and a Line Interface Unit (LIU). The device supports T1, E1, J1, and HDLC interfaces, enabling data transmission over standard digital subscriber lines. It operates with dual power supplies of 1.8V and 3.3V and functions within an industrial temperature range of -40°C to +85°C. The component is housed in a 160-LBGA surface-mount package.
