MAX9209/MAX9213
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
