Programmable DC-Balanced
21-Bit Serializers
General Description
The MAX9209/MAX9211/MAX9213/MAX9215 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/MAX9211/MAX9213/MAX9215 feature
programmable DC balance, which allows isolation
between the serializer and deserializer using AC-cou-
pling. 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/
MAX9212/MAX9214/MAX9216 deserializers decode the
data. When DC balance is not programmed, the serial-
izers are compatible with non-DC-balanced, 21-bit seri-
alizers like 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/MAX9211/MAX9213/MAX9215 are avail-
able in TSSOP and space-saving thin QFN 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.
