Table 10. Connector Descriptions
Connector Use
PWR Input that accepts a 9 V to 16 V, 6 A external DC power connector.
1G/10G ETH Two SFP+ input terminals used for 1G ETH or 10G ETH connectivity with
the host driver. Not currently supported in LabVIEW FPGA.
REF OUT Output terminal for an external reference signal for the LO on the device.
REF OUT is a female SMA connector with an impedance of 50 Ω, and it is
a single-ended reference output. The output signal at this connector is
10 MHz at 3.3 V.
REF IN Input terminal for an external reference signal for the LO on the device.
REF IN is a female SMA connector with an impedance of 50 Ω, and it is a
single-ended reference input. REF IN accepts a 10 MHz signal with a
minimum input power of 0 dBm (0.632 Vpk-pk) and a maximum input
power of 15 dBm (3.56 Vpk-pk) for a square wave or sine wave.
