PulseBlasterDDS-I-300
V. USB Connection - Connecting to the
PulseBlasterDDS-I-300-USB boards
Power Requirements
1. Recommended values and maximum currents:
•
+5V, 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.
2. 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.
3. The PulseBlasterDDS-I-300-USB requires USB 2.0 to operate.
Power Connectors
The PBDDS-USB has two power connectors wired in parallel: A 5-pin DIN-type connector and a 6-pin Molex-style
connector. The pin and signal arrangements for these two connection points are shown below in Figures 14 and 15,
respectively.
