Insert the OH300 unit into the eval board socket • Pin 1 of the OH300 should be oriented to the lower left of the fixture in the view above. • Close the clam-shell cover until it clicks. 2. Connect power • Connect the wired Vcc banana plug from TP3/TP4 to the appropriate 3.3V or 5V power supply capable of supplying ~ 1.2A of current. • Do not use the J5 “VCC” BNC for the power connection. 3. Connect output: • For CMOS outputs, connect the “CMOS OUT” BNC J6 to an oscilloscope or frequency counter input. Use a high impedance probe if possible. • For Sinewave outputs, connect the “RF OUT” BNC J9 using a coaxial cable to a 50ohm scope or frequency counter input. 4. Connect voltage control: • For OH300-series parts with voltage control (VCOCXO) option, connect J10 “CV IN” BNC to the appropriate +1.65Vdc or +2.5Vdc supply.
