RadioProcessor
Recommended values and maximum currents for RadioProcessorUSB Power:
+5 V, 2.0 A (Digital Section)
+6 V, 1.0 A (Analog Section, Positive Voltage)
-6 V, 0.2 A (Analog Section, Negative Voltage)
All three voltages need to be applied simultaneously or damage to the board will result.
Two independent grounds exist: Digital Ground and Analog Ground. Power sources should be connected
as follows:
•
Digital Ground should be connected to the ground point of +5 V supply.
•
Analog Ground should be connected to the center point (Ground Point) of the +6V and -6V supplies.
If you will be making your own power supply to connect to the Molex-style power connector, you will need
the following parts or their equivalents: One 6-pin female Mini-Fit Jr.™ connector (DigiKey part No.
WM23702-ND) and six Mini-Fit Jr.™ crimp receptacles (DigiKey part No. WM2501-ND).
Warning:
Do not connect PEG (PCI Express Graphics) power connectors available in some computers
directly to the 6-position Molex-style power connector. Doing so will cause irreparable damage to the board.
SpinCore Technologies is not liable for any damage caused by this.
RF Connectors
The RadioProcessorUSB has two Female SMA Jack connectors for RF signals. These connectors are
labeled as RF Out and RF In for the transmitter output and receiver input respectively.
Digital Output Connector
The digital outputs of the RadioProcessorUSB are present on both the J300 and J301 connectors. J300 is
a standard DB-9 connector and J301 is a 5x2 shrouded IDC header. The pinouts of these connectors and the
corresponding signal names are shown below in Figures 16 and 17 and Tables 8 and 9 respectively.
