KIT34670EGEVBE Evaluation Board, Rev. 1.0 Freescale Semiconductor 3 Important Notice
2 Important Notice
Freescale provides the enclosed product(s) under the following conditions: This evaluation kit is intended for use of ENGINEERING DEVELOPMENT OR EVALUATION PURPOSES ONLY. It is provided as a sample IC pre-soldered to a printed circuit board to make it easier to access inputs, outputs, and supply terminals. This EVB may be used with any development system or other source of I/O signals by simply connecting it to the host MCU or computer board via off-the-shelf cables. This EVB is not a Reference Design and is not intended to represent a final design recommendation for any particular application. Final device in an application will be heavily dependent on proper printed circuit board layout and heat sinking design as well as attention to supply filtering, transient suppression, and I/O signal quality. The goods provided may not be complete in terms of required design, marketing, and or manufacturing related protective considerations, including product safety measures typically found in the end product incorporating the goods. Due to the open construction of the product, it is the user's responsibility to take any and all appropriate precautions with regard to electrostatic discharge. In order to minimize risks associated with the customers applications, adequate design and operating safeguards must be provided by the customer to minimize inherent or procedural hazards. For any safety concerns, contact Freescale sales and technical support services. Should this evaluation kit not meet the specifications indicated in the kit, it may be returned within 30 days from the date of delivery and will be replaced by a new kit. Freescale reserves the right to make changes without further notice to any products herein. Freescale makes no warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does Freescale assume any liability arising out of the application or use of any product or circuit, and specifically disclaims any and all liability, including without limitation consequential or incidental damages. “Typical” parameters can and do vary in different applications and actual performance may vary over time. All operating parameters, including “Typical”, must be validated for each customer application by customer’s technical experts. Freescale does not convey any license under its patent rights nor the rights of others. Freescale products are not designed, intended, or authorized for use as components in systems intended for surgical implant into the body, or other applications intended to support or sustain life, or for any other application in which the failure of the Freescale product could create a situation where personal injury or death may occur. Should Buyer purchase or use Freescale products for any such unintended or unauthorized application, Buyer shall indemnify and hold Freescale and its officers, employees, subsidiaries, affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that Freescale was negligent regarding the design or manufacture of the part.Freescale™ and the Freescale logo are trademarks of Freescale Semiconductor, Inc.

KIT34670EGEVBE Evaluation Board, Rev. 1.0 Freescale Semiconductor 4 Using the EVB
3 Using the EVB
Warning: Always wear Safety Glasses when working around electronic modules and when soldering. 1. The KIT34670EGEVBE is ready for use. However, to change the class of the PD, set jumper P4 to the desired position. Connect your Ethernet cable from the PoE switch or hub to the left RJ45 connector on the board. The Ethernet cable going to your application must be plugged into the right RJ45 connector. 2. Solder two wires onto the VO and SGND pads (right, upper corner of board) and connect or solder the wires to your applications supply input lines. The board delivers 5V, so make sure your application accepts 5V. Watch the correct polarity when connecting the wires to your application. 3. To change the oscillator frequen cy from the default value to your frequency of choice, remove jumper P3 and use R12 to adjust the frequency. The EVB must be in normal operating mode (GATE switching) to adjust the frequency. Connect an oscillocope between pin 19 (GATE) and pin 11, 12, or 13 (VOUT) of the MC34670 and control the frequency during your adjustment. Also control VO on the board with a voltmeter. This adjustment should be made without an application connected. 4. To change the inrush current limit, exchange resistor R8 with an appropriate resistor value. Please read the MC34670 datasheet or application note A/N3279 (CD-ROM) for adjusting the inrush current limit and proper resistor value. The board is pre-setup with the default (highest) inrush current limit compliant to IEEE802.3af. 5. To change the UVLO setting, two resistors must be altered, R2 and R7. To find the correct values for the resistors, please refer to the datasheet or application note. The board is pre-setup with the default values for the UVLO setting compliant to IEEE802.3af.
