... AVDD, DVDD, VCC_USB, and V_OSC/VCP. Shown in Table 1, these domains provide power to the analog and digital portion of the AD9510, the charge pump in the PLL and VCO/VCXO, as well as USB communication circuitry. These four domains do not require four distinct power supplies however, as the analog, digital, and USB domains always run at 3 ...

... FUNCTIONS PLL Section The AD9510 on-chip PLL consists of a programmable reference divider, a programmable feedback divider, a phase-frequency detector, and charge pump. All are represented as list boxes in the PLL section (Figure 16) of the main interface window of the software. Additionally, the PLL section includes list boxes for PLL reference settings and one for the status pin output. ...

... AND RESET In addition, there are check boxes to reset both counters or to bypass the B counter. For more information on the N divider setup, please refer to the AD9510 data sheet. Phase Frequency Detector (PFD) Window Figure 19 shows the PFD window, which gives you control over the following PFD functions: • ...

... The charge pump settings window (Figure 20) allows you to select one of four different charge pump modes: tri-state, pump up, pump down, and normal operation. For more information on the four charge pump settings, please refer to the AD9510 data sheet. Figure 19. Phase Frequency Detector Window Figure 20 ...

... It is located in the upper right-hand corner of the PLL section (see Figure 16). Changing this resistor alters the lowest charge pump current setting and the charge pump current increment. The CP Rset value defaults to 5.1 kΩ, which is how the AD9510 evaluation board is shipped. If you want to change this value, the software accepts Rset values between 3.1 kΩ and 11 kΩ. You must also change the physical CP Rset resistor value on the evaluation board itself ...

... AD9510/PCB Clock Inputs Section Figure 23 shows the clock inputs section of the main interface window. It contains the settings for the three clock inputs: REFCLK, CLK1, and CLK2. These list boxes let you input the clock frequencies so that the PLL and output frequencies can be calculated automatically. ...
Page 19
... The output frequency of the eight outputs is calculated from the divider settings and the specified input clock frequency then displayed on the right-hand side of the clock distribution section. If the calculated output frequency exceeds the rated driver frequency, the displayed frequency appears in red. Figure 25. Clock Distribution Section, Main Interface Window Rev Page AD9510/PCB ...

... AD9510/PCB Control Functions Section The AD9510 has a number of sync and reset functions. These are controlled by the drop-down box, check boxes, and command buttons located on the lower left-hand side of the main interface window (see Figure 28). Function Pin Settings The function pin can be set for three different functions. The three options are Reset_B, Sync_B, and Powerdown_B, which are accessible from the drop-down menu under Function Pin Control ...
