Product Summary

The LXT6155LE B5 is a high speed fully integrated transceiver designed for 155 Mbps SDH/SONET/ATM transmission system applications. The LLXT6155LE B5 provides a LVPECL interface for fiber optics modules, and a CMI interface for coax cable drive. The LXT6155LE B5 is implemented using Level One’s proven low power 3.3V CMOS analog and digital circuits.
