Evaluates: MAX9209/MAX9244 19-4270 Rev 0 9/08 MAX9209/MAX9244 Evaluation Kit General Description Features 21-Bit Parallel LVCMOS/LVTTL Interface The MAX9209/MAX9244 evaluation kit (EV kit) provides a proven design to evaluate the MAX9209 21-bit pro- 8-Conductor Connector with Custom Cable grammable DC-balanced serializer and the MAX9244 Independent Evaluation of the MAX9209/MAX9244 21-bit deserializer with programmable spread spectrum Serializer/Deserializer (SerDes) and DC balance. The MAX9209 serializes 21 bits of Lead-Free and RoHS Compliant LVCMOS/LVTTL parallel input data to three LVDS out- Proven PCB Layout puts. The MAX9244 deserializes the three LVDS input data from the MAX9209 and transforms it back to 21-bit Fully Assembled and Tested LVCMOS/LVTTL parallel data. Ordering Information The MAX9209/MAX9244 EV kit circuits are implement- PART TYPE ed on a single PCB and come with a MAX9209EUM+ MAX9209EVKIT+ and a MAX9244EUM+ installed. or EV Kit MAX9244EVKIT+ +Denotes lead-free and RoHS compliant. Note: The MAX9209/MAX9244 EV kit can be ordered using either part number.
