MAX9257A/MAX9258A Evaluation Kit
By default, the MAX9258A, MAX9257A, and the emulat-
ed 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 but-
tons to demonstrate several simple communication
trans-actions between the ECU and the camera.
A user can change the UART speed, enable/disable
the video clocks (PCLK_IN, HSYNC_IN, and
VSYNC_IN), select different video clock speeds, and
switch the camera to the I
Configuration Examples section for details.
The EV kit can generate PCLK_IN, HSYNC_IN, and
VSYNC_IN signals with the following relationships:
HSYNC_IN = PCLK_IN/1000 and VSYNC_IN =
PCLK_IN/500000. By default they are not enabled, so

C interface. See the
that an external pattern generator or piece of video
equipment can be connected to J6. If the Enable
PCLK_IN/HSYNC_IN/VSYNC_IN button is pressed, the
signals are enabled and the status of these three sig-
nals are displayed in the Onboard PCLK_IN,
HSYNC_IN, VSYNC_IN Status group box.
By default, PCLK_IN is 30MHz, HSYNC_IN is 30kHz,
and VSYNC_IN is 60Hz. The duty cycles of all the sig-
nals are fixed at 50%.
This section describes how to configure the SerDes to
work in UART Never Come Back Operation, UART
With Finite CTO Operation, and I
oscilloscope to monitor the activity on the MAX9258A
TX, RX, and CCEN pins.
