Programmable Dc-balanced 21-bit Serializers

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 -40C to +85C temperature range.
