Datasheet

General Description
The MAX9209/MAX9213 serialize 21 bits of LVTTL/
LVCMOS parallel input data to three LVDS outputs. A
parallel rate clock on a fourth LVDS output provides
timing for deserialization.
The MAX9209/MAX9213 feature programmable DC bal-
ance, which allows isolation between the serializer and
deserializer using AC-coupling. The DC balance circuits
on each channel code the data, limiting the imbalance
of transmitted ones and zeros to a defined range. The
companion MAX9210/MAX9214 deserializers decode
the data. When DC balance is not programmed, the
serializers are compatible with non-DC-balanced, 21-bit
serializers such as the DS90CR215 and DS90CR217.
Two frequency ranges and two DC-balance default
conditions are available for maximum replacement flexi-
bility and compatibility with existing non-DC-balanced
serializers.
The MAX9209/MAX9213 are available in TSSOP and
space-saving TQFN packages.
