1. Quick Start - Board Configuration Check List
Mount your oscillator device on the board at appropriate oscillator site location (U1, U2, or U3, but on only one location) if a device is
not yet mounted.
1. Start with EVB board powered down/off.
2. Set DIP switches (described in Section
5. Control Signal Switch Settings ) for your specific device:
a. Look up your device as appropriate in the tables of Sections 6. Supported Devices - Stand-Alone Mode or 7. Supported Devi-
ces - Software Controlled Mode - I
2
C .
b. Make DIP switch settings per table entry for pins 1,2,7,8 as appropriate. See Sections 6. Supported Devices - Stand-Alone
Mode or 7. Supported Devices - Software Controlled Mode - I
2
C .
3. Verify output termination is appropriate for your device (see Section 9. Output Clock Terminations for more info).
4. Set +5V Select switch (SW5) based on how you will power the EVB, either via USB or via ex5V supply.
5. Connect power, either via USB port or ex5V power supply as chosen in previous step.
6. Output Clocks:
• For pin controlled oscillators, clock output should be available on output SMAs of DUT site in use.
• For I2C oscillators, run appropriate configuration software (e.g.,
Programmable Oscillator Software tool ) and perform device
configuration to get desired output clock.
