General Description
The MAX9257 serializer pairs with the MAX9258 deseri-
alizer to form a complete digital video serial link. The
MAX9257/MAX9258 feature programmable parallel data
width, parallel clock frequency range, spread spectrum,
and preemphasis. An integrated control channel trans-
fers data bidirectionally at power-up during video blank-
ing 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 MAX9258, hence
eliminating the need for an external reference clock.
The MAX9257 serializes 10, 12, 14, 16, and 18 bits with
the addition of two encoding bits for AC-coupling. The
MAX9258 deserializer links with the MAX9257 to deseri-
alize 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, depend-
ing 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 MAX9258 receives programming instructions from
the electronic control unit (ECU) during the control
channel and transmits to the MAX9257 over the serial
video link. The instructions can program or update the
MAX9257, MAX9258, or an external peripheral device,
such as a camera. The MAX9257 communicates with
the peripheral device with I2C or UART.
The MAX9257/MAX9258 operate from a +3.3V core
supply and feature separate supplies for interfacing to
+1.8V to +3.3V logic levels. These devices are avail-
able in 40-lead TQFN or 48-pin LQFP packages. These
devices are specified over the -40°C to +105°C temper-
ature range.
