19-3103; Rev 0; 12/07 Multirate CDR with Integrated Serializer/Deserializer for GPON and BPON ONT Applications General Description The MAX3886 2.488Gbps/1.244Gbps/622Mbps CDR with SerDes (serializer/deserializer) is designed specifically for low-cost optical network terminal (ONT) applications in Gigabit passive optical network (GPON) and broadband passive optical network (BPON) fiber-tothe-home (FTTH) systems. It provides G.984- and G.983-compliant clock and data recovery (CDR) for the www.DataSheet4U.com continuous downstream data signal, with an integrated 4-bit SerDes that has LVDS parallel interfaces and CML serial interfaces. The SerDes uses the recovered downstream clock for upstream serialization (loopback clock), providing optimum PON operation.
