Part Details:

19-1044; Rev 0; 6/08 EVALUATION KIT AVAILABLE Fully Programmable Serializer/Deserializer with UART/I2C Control Channel MAX9257/MAX9258 General Description Features The MAX9257 serializer pairs with the MAX9258 deseri- 10/12/14/16/18-Bit Programmable Parallel Data alizer to form a complete digital video serial link. The Width MAX9257/MAX9258 feature programmable parallel data MAX9258 Does Not Require Reference Clock width, parallel clock frequency range, spread spectrum,and preemphasis. An integrated control channel trans- Parity Protection for Video and Control Channels fers data bidirectionally at power-up during video blank- Programmable Spread Spectrum ing over the same differential pair used for video data. Programmable Rising or Falling Edge for HSYNC, This feature eliminates the need for external CAN or LIN VSYNC, and Clock interface for diagnostics or programming. The clock isrecovered from input serial data at MAX9258, hence Up to 10 Remotely Programmable GPIO on eliminating the need for an external reference clock. MAX9257 The MAX9257 serializes 10, 12, 14, 16, and 18 bits with Automatic Resynchronization in Case of Loss of the addition of two encoding bits for AC-coupling. The Lock MAX9258 deserializer links with the MAX9257 to deseri- MAX9257 Parallel Clock Jitter Filter PLL with alize a maximum of 20 (data + encoding) bits per Bypass pixel/parallel clock period for a maximum serial-data DC-Balanced Coding Allows AC-Coupling rate of 840Mbps. The word length can be adjusted toaccommodate a higher pixel/parallel clock frequency. 5 Levels of Preemphasis for Up to 20m STP Cable The pixel clock can vary from 5MHz to 70MHz, depend- Drive ing on the serial-word length. Enabling parity adds two Integrity Test Using On-Chip Programmable parity bits to the serial word. The encoding bits reduce PRBS Generator and Checker ISI and allow AC-coupling. LVDS I/O Meet ISO10605 ESD Protection (±10kV The MAX9258 receives programming instructions from Contact and ±30kV Air Discharge) the electronic control unit (ECU) during the control LVDS I/O Meet IEC61000-4-2 ESD Protection channel and transmits to the MAX9257 over the serial (±8kV Contact and ±20kV Air Discharge) video link. The instructions can program or update theMAX9257, MAX9258, or an external peripheral device, LVDS I/O Meet ±200V Machine Model ESD such as a camera. The MAX9257 communicates with
