  • Pin 1 of the unit will be placed in the topmost position of LIF receptacle J12.
  • Pin 1 is indicated on the evaluation board with a large silkscreen “1”.
  • Press the unit down firmly- there should be no metal pins exposed. 2) DIP Switch Manual Control Using SW1
  • Verify that all the DIP switches are turned “On” (rightmost position).
  • “Off” position applies a logic low to the unit, “On” position applies a logic high. Switch Label Function Sync1 Controls DUT pin 19 “SYNC1 control” Sync2 Controls DUT pin 20 “SYNC2 control” Disable Controls DUT pin 21 (/Disable) Boot Select Controls DUT pin 8 (/Bootsel) - Only used for Wi125 software updates/revisions Reset Controls DUT pin 10 (/Reset) 3) Connect the BNCs (center positive)
  • Do not apply voltages higher than indicated or the DUT and/or test board could be damaged.
  • Connect 3.3V to J1 to power the test board.
  • Connect 3.3V to both J2 and J3 to power the FTS125. Use separate supplies for J2 “DUT Vcc1” and J3 “DUT Vcc2” otherwise phase noise performance will be degraded.
  • Connect 3-12V to J4 to power an active antenna through the FTS125's MCX antenna connector. If a different antenna is used other than that supplied with the FTS125 Eval Board, consult that antenna's documentation for the required voltage.

  • Used to monitor NMEA 0183 data stream.
  • NS3KView software is recommended for use and can be provided per request.
  • Baud Rate: 38400.
  • Refer to the Wi125 GPS Receiver User Manual for more information on NMEA and the proprietary messages and commands. 5) Connect a full sky view GPS antenna to the DUT’s female MCX connector. 6) Power the unit on. 7) LED Function
  • Antenna Fault Status (D7) Red LED turns on if a fault condition is indicated on DUT Pin 25. An antenna fault condition is defined as an overcurrent on DUT Pin 14 (Antenna Supply Voltage). This fault status is self-clearing once the fault condition goes away.
  • Holdover Status (D6) Amber LED turns on if the unit is in automatic or forced holdover as indicated by DUT Pin 23 “Holdover Status”.
  • Lock Status (D5) Green LED turns on if the unit is tightly locked to the selected input as indicated by DUT Pin 24 “Lock Status”. Available at Digi-Key www.digikey.com
