The MAX9248/MAX9250 digital video serial-to-parallel converters deserialize a total of 27 bits during data and control phases. In the data phase, the LVDS serial input is converted to 18 bits of parallel video data and in the control phase, the input is converted to 9 bits of parallel control data. The separate video and control phases take advantage of video timing to reduce the serial-data rate. The MAX9248/MAX9250 pair with the MAX9247 serializer to form a complete digital video transmission system. For operating frequencies less than 35MHz, the MAX9248/MAX9250 can also pair with the MAX9217 serializer. 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.
