MAX9217

19-3558; Rev 2; 10/05 www.DataSheet4U.com 27-Bit, 3MHz-to-35MHz DC-Balanced LVDS Serializer General Description The MAX9217 digital video parallel-to-serial converter serializes 27 bits of parallel data into a serial data stream. Eighteen bits of video data and 9 bits of control data are encoded and multiplexed onto the serial interface, reducing the serial data rate. The data enable input determines when the video or control data is serialized. The MAX9217 pairs with the MAX9218 deserializer to form a complete digital video serial link. Interconnect can be controlled-impedance PC board traces or twistedpair cable. Proprietary data encoding reduces EMI and provides DC balance. DC balance allows AC-coupling, providing isolation between the transmitting and receiving ends of the interface. The LVDS output is internally terminated with 100Ω. ESD tolerance is specified for ISO 10605 with ±10kV contact discharge and ±30kV air discharge. The MAX9217 operates from a +3.3V core supply and features a separate input supply for interfacing to 1.8V to 3.3V logic levels. This device is available in 48-lead Thin QFN and TQFP packages and is specified from -40°C to +85°C.
