27-Bit, 2.5MHz-to-42MHz  
DC-Balanced LVDS Serializer  
MAX9247  
General Description  
Features  
o Preemphasis Improves Eye Diagram and Signal  
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.  
Integrity at the Output  
o Proprietary Data Encoding for DC Balance and  
Reduced EMI  
o Control Data Sent During Video Blanking  
o Five Control Data Inputs are Single-Bit-Error  
Tolerant  
The MAX9247 pairs with the MAX9248/MAX9250 dese-  
rializers to form a complete digital video serial link.  
Interconnect can be controlled-impedance PCB 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 100. For operating frequen-  
cies less than 35MHz, the MAX9247 can also pair with  
the MAX9218 deserializer.  
o Programmable Phase-Shifted LVDS Signaling  
Reduces EMI  
o Output Common-Mode Filter Reduces EMI  
o Greater Than 10m STP Cable Drive  
o Wide ±±2 Reference Clock Tolerance  
o ISO 10605 and IEC 61000-4-± Level 4  
ESD Protection  
o Separate Input Supply Allows Interface to 1.8V  
to 3.3V Logic  
ESD tolerance is specified for ISO 10605 with 10kV  
Contact Discharge and 30kV Air-ꢀap Discharge.  
o +3.3V Core Supply  
o Space-Saving LQFP Package  
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 a 48-lead  
LQFP package and is specified from -40°C to +85°C or  
-40°C to +105°C.
