Abstract :
A dispersion tolerant receiver for fiber-optic links, in 0.18 mum SiGe BiCMOS, implements a Class-2 partial response maximum likelihood (PRML) equalization entirely in the analog domain. Post-FEC error free operation is achieved with data received from over 400 km of uncompensated single mode fiber (SMF). The receiver complies with XFI Jitter specifications for Telecom (SONET OC-192 and G.709 ldquoOTU-2rdquo).
