Product Details
The MAX9248 features spread-spectrum capability, allowing output data and clock to spread over a specified frequency range to reduce EMI. The data and clock outputs are programmable for a spectrum spread of ±4% or ±2%. The MAX9250 features output enable input control to allow data busing.
Proprietary data decoding reduces EMI and provides DC balance. The DC balance allows AC-coupling, providing isolation between the transmitting and receiving ends of the interface. The MAX9248/MAX9250 feature a selectable rising or falling output latch edge.
ESD tolerance is specified for ISO 10605 with ±10kV Contact Discharge and ±30kV Air-Gap Discharge.
The MAX9248/MAX9250 operate from a +3.3V ±10% core supply and feature a separate output supply for interfacing to 1.8V to 3.3V logic-level inputs. These devices are available in a 48-lead LQFP package and are specified from -40°C to +85°C or -40°C to +105°C.
Key Features
- Programmable ±4% or ±2% Spread-Spectrum Output for Reduced EMI (MAX9248)

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