EVK-UFT285-6-7 Evaluation Board User Guide
USER GUIDE
Introduction
The EVK-UFT285-6-7 is designed to help the customer evaluate the 8T49N285, 8T49N286, and 8T49N287 devices, members
of IDT's 3rd generation Universal Frequency Translator family. When the board is connected to a PC running IDT Timing
Commander™ software through USB, the device can be configured and programmed to generate frequencies with best-in-class
performances.
Contents
The EVK-UFT285-6-7 evaluation board ships with the following:
• 1 – EVK-UFT285-6-7 Evaluation Board
• 1 – USB Cable
Requirements
1. PC Requirements:
• IDT Timing Commander software installed.
• USB 2.0 interface. The evaluation board USB module is not compatible with USB 3.0. If using a computer with high speed
USB ports, please check if there's a standard USB 2.0 port available for use. The hardware drivers are automatically
installed during the Timing Commander installation.
• Windows XP SP3 or later.
• Processor: Minimum 1GHz.
• Memory: Minimum 512MB, recommended 1GB.
• Available Disk Space: Min 600MB (1.5GB 64bit), recommended 1GB (2GB 64bit)
• Network access during installation if the .NET framework is not currently installed on the system.
2. Power Supply with 3.3V and 1000mA rating
3. Three banana plug cables to connect the power supply to the board.
Quick Start: Powering Up the Board
(1) Set 3.3V supply current limit to 500mA.
(2) Remove all output terminations.
(3) Set Dip Switch selectors to the middle position.
(4) Connect a cable from a PC to the USB port.
(5) Connect VEE to the black GND jack.
(6) Connect 3.3V to VCC_J and VDDO_J.
(7) Power on the Power Supply.
(8) Press the Reset Button.
Once correct operation is verified, set the power supply limit for the number of outputs to be active.
The USB port must be powered by the PC in order to have the correct I
The board ships with a 38.88MHz crystal and will have a default frequency of 155.52MHz on Q0. If all outputs are unterminated,
current should measure ~256mA with 3.3V on VCC_J and VDDO_J. If all outputs are terminated, current should measure
~262mA.
When evaluating performance with the default hardware configuration, it is recommended that all active outputs be terminated
50ohms to VEE by either terminator plugs or an instrument.
