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-coupling. The DC balance circuits of MAX9209 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.
