2.3 Quick-Start Procedure

Note: Do not turn on power supply until all connections to the device are made to the board.

The procedures listed below are the steps for a quick-start set-up using channel A.

  1. Set VCCI/VCCO Power Supply to 5.0 V and disable the power supply output.
  2. Since the same power supply is used for both VCCI and VCCO, connect positive terminal supply to TP5 and TP3, and negative terminal to TP6.
  3. Connect VEE and GND via jumper J17 and J3.
  4. Connect SHDNA to VCCO via jumper J1 and SHDNB to VEE via jumper J13. This sets Channel A in active mode and Channel B in shutdown mode.
  5. Verify that cables connecting to IN+A SENSE, OUT+A, and OUT-A are matched length and impedance. Perform any de-skewing if necessary. Set the function generator (50-Ω terminated) to produce a square wave output with 400mVpp at 10 MHz, with a DC offset of 0.300 V. Disable the signal generator output. Connect the output to IN+A.
  6. Set one of the outputs of the DC power supply to 300 mV. Disable the power supply output. Connect the output to IN-A.
  7. Connect OUT+A and OUT-A to a 50-Ω terminated channel on the oscilloscope.
  8. Connect IN+A SENSE, to another 50-Ω terminated scope channel.
  9. Enable the VCCI/VCCO power supply.
  10. Verify the total supply current is < 18 mA.
  11. Enable the signal generator.
  12. Monitor and verify the inputs from IN+A SENSE.
  13. Monitor and verify the outputs for OUT+A and OUT-A.
