EVALUATION KIT AVAILABLE MAX9248/MAX9250 27-Bit, 5MHz to 42MHz DC-Balanced LVDS Deserializers General Description Benefits and Features The MAX9248/MAX9250 digital video serial-to-parallel Programmable 4% or 2% Spread-Spectrum converters deserialize a total of 27 bits during data and Output for Reduced EMI (MAX9248) control phases. In the data phase, the LVDS serial input Proprietary Data Decoding for DC Balance and is converted to 18 bits of parallel video data and in the Reduced EMI control phase, the input is converted to 9 bits of parallel Control Data Deserialized During Video Blanking control data. The separate video and control phases take advantage of video timing to reduce the serial-data rate. Five Control Data Inputs are Single-Bit-Error Tolerant The MAX9248/MAX9250 pair with the MAX9247 serializer Output Transition Time is Scaled to Operating to form a complete digital video transmission system. For Frequency for Reduced EMI operating frequencies less than 35MHz, the MAX9248/ Staggered Output Switching Reduces EMI MAX9250 can also pair with the MAX9217 serializer. Output Enable Allows Busing of Outputs (MAX9250) The MAX9248 features spread-spectrum capability, allow- Clock Pulse Stretch on Lock ing output data and clock to spread over a specified fre- quency range to reduce EMI. The data and clock outputs Wide 2% Reference Clock Tolerance are programmable for a spectrum spread of 4% or 2%. Synchronizes to MAX9247 Serializer Without The MAX9250 features output enable input control to External Control allow data busing. ISO 10605 and IEC 61000-4-2 Level 4 ESD Proprietary data decoding reduces EMI and provides DC Protection balance. The DC balance allows AC-coupling, providing Separate Output Supply Allows Interface to 1.8V isolation between the transmitting and receiving ends of to 3.3V Logic the interface. The MAX9248/MAX9250 feature a select- able rising or falling output latch edge. +3.3V Core Power Supply ESD tolerance is specified for ISO 10605 with 10kV Space-Saving LQFP Package Contact Discharge and 30kV Air-Gap Discharge. -40C to +85C and -40C to +105C Operating The MAX9248/MAX9250 operate from a +3.3V 10% Temperature Ranges 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 -40C to +85C or -40C to +105C.
