Quick Start
The MAX9507 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Carefully connect the boards by aligning the 20-pin
connector of the MAX9507 EV kit with the 20-pin
header on the CMAXQUSB+ interface board.
Gently press them together.
2) Connect the power-supply ground to the GND pad
on the EV kit.
3) Connect the 1.7V to 2.625V supply to the VDD pad
on the EV kit.
4) Connect the output of the video signal generator to
the VIDIN BNC connector on the EV kit. The video
signal must be biased such that the sync tip is at
ground and sets the full-scale video signal to
0.25V P-P .
5) Connect the VIDOUT BNC connector on the EV kit
to the input of the video measurement equipment.
Detailed Description of Software
User-Interface Panel
In the program’s main window (Figure 1), a mouse is
used to toggle the checkboxes that control the various
features of the MAX9507. The MAX9507 EV kit software
permits the control of software-configurable features:
switches, sync-tip clamp, filter, signal path, charge
pump, load change flag enable, automatic signal path
enable, and automatic charge pump enable. Changes
to the controls result in write operations that update the
configuration and video load detect registers of the
MAX9507. All changes to the 8-bit command registers
are reflected on screen under the B7–B0 labels; the
register contents are also read and displayed in hexa-
decimal format.
The EV kit software gives the user the option to automat-
ically read both registers, or manually read each regis-
ter individually by toggling the Enable AutoPolling
checkbox. With AutoPolling disabled, the user must
manually click the Read button located next to the hex
register contents in order to send a read command. A
memo box at the bottom of the program’s main window
displays descriptions of the various features provided.
Place the pointer over the bit names for a functional
description. The status bar at the bottom of the pro-
gram’s main window is used to verify command module
and device connectivity.
