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-to-the-home (FTTH) systems. It provides G.984- and G.983-compliant clock and data recovery (CDR) for the 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. The CDR frequency reference can be provided by a low-cost 19.44MHz SMD-type crystal or external LVCMOS source, and excellent jitter tolerance supports applications requiring FEC. An integrated burst-enable signal path also simplifies high-performance upstream burst timing.
This 3.3V IC is housed in a 8mm x 8mm, 56-lead thin QFN package and operates from -40°C to +85°C.
