1. Introduction
The OM6293 evaluation board features RJ45 jacks for easy setup and demonstration of
the bus buffer capabilities of the PCA9600. It can be easily connected to other boards with
off-the-shelf telephone or networking twisted pair wires.

2. Features
• A complete evaluation platform for the PCA9600
• Easy to integrate daughter card
• Convenient test point for easy scope measurements and signal access
3. Getting started
3.1 Assumptions
Familiarity with the I2C-bus is recommended. It is also recommended that the user read
Application Note AN10658, which covers other design considerations such as timing
delays, maximum data transmission speeds, handling gr ound potential differences and
designing for extreme ESD requirements.
3.2 Static handling requirements

CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
during transport and handling. You must use a ground strap or touch the PC case or other
grounded source before unpacking or handling the hardware.
3.3 System requirements
The OM6293 daughter card can be used with the Windows based OM6275 I2C 2005-1
demo board, the microcontroller-based OM6299 industrial reference design board, or
stand-alone in the user’s application.
3.4 Power supply
When connected to the OM6275 I2C 2005-1 demo board or the OM6299 industrial
reference design board, the OM6293 can draw power from the host board through the
5 V pin on connector 3 (CON3).
An external power supply can also be used to power the board at location J1. The external
power supply can range from 2.5 V to 15 V.
