Bench Power Supply An external power supply can be used by connecting jumper J20 between the central pin and the VDD J position. VDD J must then be connected to the appropriate power supply for the device ordered. 9FGL= 3.3V 9FGV= 1.8V 9FGU = 1.5V USB Power Supply When the board is connected to a PC through a USB cable, on-board voltage regulators can supply the appropriate voltage to the clock chip. USB power is selected by connecting J20 between the central pin and the VDD USB pin. Depending on the evaluation board ordered, the R22 resistor will be pre-populated as follows: For VDD = 1.5V: R22 = 49.9 For VDD = 1.8V: R22 = 107 For VDD = 3.3V: R22 = 402 Figure 2. Connecting the jumper to VDD J or VDD USB. Default is to power by USB 2 REVISION C 10/26/15
