The MAX9257A serializer pairs with the MAX9258A

deseri alizer to form a complete digital video serial link.

The devices 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 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

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 accom-

modate 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 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 I

The devices operate from a +3.3V core supply and fea-

ture 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 -40NC to +105NC temper ature range.
