MAX9217 19-3558 Rev 4 8/09 27-Bit, 3MHz-to-35MHz DC-Balanced LVDS Serializer General Description Features The MAX9217 digital video parallel-to-serial converter Proprietary Data Encoding for DC Balance and Reduced EMI serializes 27 bits of parallel data into a serial data stream. Eighteen bits of video data and 9 bits of control data are Control Data Sent During Video Blanking encoded and multiplexed onto the serial interface, reduc- Five Control Data Inputs Are Single-Bit-Error ing the serial data rate. The data enable input determines Tolerant when the video or control data is serialized. Output Common-Mode Filter Reduces EMI The MAX9217 pairs with the MAX9218 deserializer to Greater than 10m STP Cable Drive form a complete digital video serial link. Interconnect can be controlled-impedance PCB traces or twisted-pair Wide 2% Reference Clock Tolerance cable. Proprietary data encoding reduces EMI and pro- ISO 10605 ESD Protection vides DC balance.
