MAX9257AGTL/V+ by Analog Devices

Programmable Serializer/Deserializer with UART/I²C Control Channel


The MAX9257A serializer pairs with the MAX9258A deserializer to form a complete digital video serial link. The MAX9257A/MAX9258A feature programmable parallel data width, parallel clock frequency range, spread spectrum, and preemphasis. An integrated control channel transfers data bidirectionally at power-up during video blanking over the same differential pair used for video data. This feature eliminates the need for external CAN or LIN interface for diagnostics or programming. The clock is recovered from input serial data at MAX9258A, hence eliminating the need for an external reference clock. The MAX9257A serializes 10, 12, 14, 16, and 18 bits with the addition of two encoding bits for AC-coupling. The MAX9258A deserializer links with the MAX9257A to deserialize a maximum of 20 (data + encoding) bits per pixel/parallel clock period for a maximum serial-data rate of 840Mbps. The word length can be adjusted to accommodate a higher pixel/parallel clock frequency. The pixel clock can vary from 5MHz to 70MHz, depending on the serial-word length. Enabling parity adds two parity bits to the serial word. The encoding bits reduce ISI and allow AC-coupling. The MAX9258A receives programming instructions from the electronic control unit (ECU) during the control channel and transmits to the MAX9257A over the serial video link. The instructions can program or update the MAX9257A, MAX9258A, or an external peripheral device, such as a camera. The MAX9257A communicates with the peripheral device with I²C or UART. The MAX9257A/MAX9258A operate from a +3.3V core supply and feature separate supplies for interfacing to +1.8V to +3.3V logic levels. These devices are available in 40-lead TQFN or 48-pin LQFP packages. These devices are specified over the -40°C to +105°C temperature range.
