General Description

The MAX9257A/MAX9258A evaluation kit (EV kit) con-

sists of a MAX9257A/MAX9258A evaluation board and

software. The EV kit is a fully assembled and tested PCB

that evaluates the MAX9257A serializer and the

MAX9258A deserializer (SerDes). The EV kit also emu-

lates an electronic control unit (ECU) and a camera. The

MAX9258A receives programming instructions from the

emulated ECU during the control channel and transmits

to the MAX9257A over the serial video link. The instruc-

tions can program or update the MAX9258A,

MAX9257A, or an external peripheral device such as a

camera. The MAX9257A communicates with the periph-

eral device with either an I

C or UART interface.

The MAX9257A/MAX9258A EV kit includes Windows

2000/XP- and Windows Vista

-compatible software that

provides a simple graphical user interface (GUI) for exer-

cising the features of the MAX9257A and MAX9258A.

The EV kit is connected to a PC through the USB.

MAX9257A/MAX9258A Evaluation Kit Software—Deserializer MAX9258A Tab By default, the MAX9258A, MAX9257A, and the emulated camera use the UART interface (JU26 and JU27 shunts are set across pins 1-2). Press the Turn On D4, Turn Off D4, Fast Blink D4, and Slow Blink D4 buttons to demonstrate several simple communication trans-actions between the ECU and the camera.
