S 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 is S Up to 10 Remotely Programmable GPIO on recovered from input serial data at MAX9258A, hence MAX9257A eliminating the need for an external reference clock. S Automatic Resynchronization in Case of Loss of The MAX9257A serializes 10, 12, 14, 16, and 18 bits Lock with the addition of two encoding bits for AC-coupling. S MAX9257A Parallel Clock Jitter Filter PLL with The MAX9258A deserializer links with the MAX9257A to Bypass deserialize a maximum of 20 (data + encoding) bits per pixel/parallel clock period for a maximum serial-data rate S DC-Balanced Coding Allows AC-Coupling of 840Mbps. The word length can be adjusted to accom- S Levels of Preemphasis for Up to 20m STP Cable modate a higher pixel/parallel clock frequency. The pixel Drive clock can vary from 5MHz to 70MHz, depend ing on the S Integrity Test Using On-Chip Programmable PRBS serial-word length. Enabling parity adds two parity bits to Generator and Checker the serial word. The encoding bits reduce ISI and allow AC-coupling. S LVDS I/O Meet ISO 10605 ESD Protection (10kV Contact and 30kV Air Discharge) The MAX9258A receives programming instructions from the electronic control unit (ECU) during the control S LVDS I/O Meet IEC 61000-4-2 ESD Protection channel and transmits to the MAX9257A over the serial (8kV Contact and 20kV Air Discharge) video link. The instructions can program or update the S LVDS I/O Meet 200V Machine Model ESD MAX9257A, MAX9258A, or an external peripheral device, Protection such as a camera.
