Abstract  
I2C, bus buffer, twisted pair  
The OM6293 is an add-on to NXP Semiconductors I2C 2005-1 demo board.  
This daughter board makes it easy to test and design with the PCA9600, a  
dual bidirectional bus buffer.

PCA9600 demonstration board OM6293  
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.  
The IC communicates to the host via the I2C-bus/SMBus port and extends the buses’  
capacitive handling, increases the current handling, extends the range, and/or allows  
I2C-bus signaling via differential bus hardware.  
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 ground 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.

6. Using the OM6293 with the I2C 2005-1 demo board  
The board can be easily configured to demonstrate two common applications:  
Generating an Fm+ compatible drive signal for other application boards, and  
Driving long Cat5e communication cables in ‘4-signal’ mode using two daughter  
boards.  
6.1 Generating an Fm+ compatible drive signal  
A single daughter board is fitted to the 9-pin expansion header of the I2C 2005-1  
evaluation board and can be powered from the switched 5 V supply on that board.  
The I2C 2005-1 evaluation board’s 9-pin header signals are duplicated on the daughter  
board’s 9-pin header CON4 to allow further expansion or connection of other daughter  
cards.  
The P82B96/PCA9600 generates Fm+ signals on the 8P8C modular (RJ45) jack CON1  
that are compatible with, for example, the PCA9633 LED Demo Board Fm+ signals. To  
select this option, it is necessary to close switches 1 and 2 on the DIP switch S1 and to  
open switches 3 and 4. (The RJ45 jack CON2 should not be used.)  
The 5 V power selection jumper should be fitted between pins 2 and 3 on header J1.  
The input signals from the I2C 2005-1 evaluation board and the corresponding Fm+  
signals as delivered to the RJ45 jack CON1 are available for probing on the 8-pin header  
J2.  
For further details on this setup, refer to the Application Note AN10658, section 3.1.  
6.2 Driving long Cat5e cables in 4-signal mode  
One board is fitted to the 9-pin expansion header of the I2C 2005-1 evaluation board and  
can be powered from the switched 5 V supply of that board by fitting the jumper between  
pins 2 and 3 on header J1.  
The board is configured for driving long Cat5e cables by opening switches 1 and 2 on the  
DIP switch S1 and closing the switches 3 and 4. The cable to be driven, fitted with  
standard 8P8C modular connectors (RJ45), is fitted into the RJ45 jack CON1.The other  
end of the cable is fitted into the RJ45 jack CON2 of a second or ‘remote’  
P82B96/PCA9600 daughter board. This ‘remote’ board will derive its 5 V supply from the  
first board, via the cable and CON2. Use of CON2, with its different wiring configuration,  
provides the necessary crossover linking from Tx on one board to Rx on the other.

Ensure that the 5 V power selection jumper is fitted between pins 2 and 3 on header J1 or  
that some alternative logic supply voltage is connected to pin 2 on J1 so that there is a  
supply voltage for the I2C-bus on the Sx/Sy side of this ‘remote’ board. The cable bus  
signals will be converted back to conventional I2C-bus levels by the ‘remote’  
P82B96/PCA9600 and both the cable bus and I2C-bus signals are available for probing on  
the 8-pin header J2. They are also available on the 9-pin header CON4 in the same  
format as on the I2C 2005-1 expansion header.  
Note that only the ‘switched 5 V’ supply from the I2C 2005-1 board is used on  
CON1/CON2. The un-switched 5 V and 3.3 V supplies are not available on the Cat5e  
cable and therefore are not available on CON4 in modes where boards are linked only by  
the Cat5e cable.  
For further details on this setup, refer to Application Note AN10658, section 3.2.
