Fully Programmable Serializer/Deserializer

with UART/I C Control Channel

7/MAX9258

General Description

Features

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.

♦ 10/12/14/16/18-Bit Programmable Parallel Data

Width

♦ MAX9258 Does Not Require Reference Clock

♦ Parity Protection for Video and Control Channels

♦ Programmable Spread Spectrum

♦ Programmable Rising or Falling Edge for HSYNC,

VSYNC, and Clock

♦ Up to 10 Remotely Programmable GPIO on

MAX9257

♦ Automatic Resynchronization in Case of Loss of

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.

♦ LVDS I/O Meet ISO 10605 ESD Protection (±10kV

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.

♦ LVDS I/O Meet ±200V Machine Model ESD

Protection

♦ -40°C to +105°C Operating Temperature Range

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.
