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,
and operate from a single +3.3V supply over the -40°C
to +85°C temperature range.
