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.
