The MAX9247 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, reduc-

ing the serial-data rate. The data-enable input determines

when the video or control data is serialized.

The MAX9247 pairs with the MAX9248/MAX9250 dese-

rializers to form a complete digital video serial link.

Interconnect can be controlled-impedance PC board

traces or twisted-pair 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. For

operating frequencies less than 35MHz, the MAX9247

can also pair with the MAX9218 deserializer.

ESD tolerance is specified for ISO 10605 with ±10kV

Contact Discharge and ±30kV Air-Gap Discharge.

The MAX9247 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

TQFP and TQFN packages and is specified from

-40°C to +85°C.
