Overview

  • Preemphasis Improves Eye Diagram and Signal Integrity at the Output
  • Proprietary Data Encoding for DC Balance and Reduced EMI
  • Control Data Sent During Video Blanking
  • Five Control Data Inputs are Single-Bit-Error Tolerant
  • Programmable Phase-Shifted LVDS Signaling Reduces EMI
  • Output Common-Mode Filter Reduces EMI
  • Greater Than 10m STP Cable Drive
  • Wide ±2% Reference Clock Tolerance
  • ISO 10605 and IEC 61000-4-2 Level 4 ESD Protection
  • Separate Input Supply Allows Interface to 1.8V to 3.3V Logic
  • +3.3V Core Supply
  • Space-Saving LQFP Package
  • -40°C to +85°C and -40°C to +105°C Operating Temperature Ranges

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, reducing the serial-data rate. The data-enable input determines when the video or control data is serialized.

The MAX9247 pairs with the MAX9248/MAX9250 deserializers 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 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 a 48-lead LQFP package and is specified from -40°C to +85°C or -40°C to +105°C.

Features and Benefits

  • 27-Bit Parallel Interface
  • Rosenberger Connector (Cable Included)
  • Independent Evaluation of the MAX9247/MAX9248 Serializer/Deserializer (SerDes)
  • Proven PCB Layout
  • Fully Assembled and Tested

Product Details

The MAX9247/MAX9248 evaluation kit (EV kit) provides a proven design to evaluate the MAX9247 27-bit, 2.5MHz to 42MHz DC-balanced LVDS serializer and the MAX9248 27-bit, 2.5MHz to 42MHz DC-balanced LVDS deserializer. The MAX9247 serializes 27 bits of parallel input data, 18 bits of video, and 9 bits of control to a serial data stream. The MAX9248 deserializes the LVDS serial input, which converts to 18 bits of parallel video data and 9 bits of parallel control data.

The EV kit PCB has a MAX9247ECM+ or MAX9247GCM+ and a MAX9248ECM+ or MAX9248GCM+ installed.
