Part Manufacturer: Maxim


Part Description: MAX9248 50 DS

Part Details:

19-3943; Rev 2; 5/08 27-Bit, 2.5MHz to 42MHz DC-Balanced LVDS Deserializers MAX9248/MAX9250 General Description 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 is Proprietary Data Decoding for DC Balance and converted to 18 bits of parallel video data and in the con- Reduced EMI trol phase, the input is converted to 9 bits of parallel con-trol data. The separate video and control phases take Control Data Deserialized During Video Blanking advantage of video timing to reduce the serial-data rate. Five Control Data Inputs are Single-Bit-Error The MAX9248/MAX9250 pair with the MAX9247 serializer Tolerant to form a complete digital video transmission system. For Output Transition Time is Scaled to Operating operating frequencies less than 35MHz, the MAX9248/ Frequency for Reduced EMI MAX9250 can also pair with the MAX9217 serializer. Staggered Output Switching Reduces EMI The MAX9248 features spread-spectrum capability,allowing output data and clock to spread over a speci- Output Enable Allows Busing of Outputs fied frequency range to reduce EMI. The data and (MAX9250) clock outputs are programmable for a spectrum spread Clock Pulse Stretch on Lock of ±4% or ±2%. The MAX9250 features output enable Wide ±2% Reference Clock Tolerance input control to allow data busing. Synchronizes to MAX9247 Serializer Without Proprietary data decoding reduces EMI and provides External Control DC balance. The DC balance allows AC-coupling, pro-viding isolation between the transmitting and receiving ISO 10605 and IEC 61000-4-2 Level 4 ends of the interface. The MAX9248/MAX9250 feature a ESD Protection selectable rising or falling output latch edge. Separate Output Supply Allows Interface to 1.8V ESD tolerance is specified for ISO 10605 with ±10kV to 3.3V Logic Contact Discharge and ±30kV Air-Gap Discharge. +3.3V Core Power Supply The MAX9248/MAX9250 operate from a +3.3V ±10% Space-Saving LQFP Package core supply and feature a separate output supply for -40°C to +85°C and -40°C to +105°C Operating interfacing to 1.8V to 3.3V logic-level inputs. These Temperature Ranges devices are available in a 48-lead LQFP package andare specified from -40°C to +85°C or -40°C to +105°C.
