General Description
The MAX3886 2.488Gbps/1.244Gbps/622Mbps CDR
with SerDes (serializer/deserializer) is designed specifi-
cally for low-cost optical network terminal (ONT) appli-
cations 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 opti-
mum 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 inte-
grated 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.
