Label Function
F The Display section determines the actively selected WR or LUT number. This section includes the following:
Mode: use the drop-down menu to select either Write or LUT display mode.
WR: when the Mode is set to Write, scroll up and down to set the WR number (0 to 3) that is currently being configured and
displayed in the Filter Settings section. Changing the WR number automatically changes the Mode to Write.
LUT: when the Mode is set to LUT, scroll up and down to set the LUT number (0 to 127) that is currently being configured and
displayed in the Filter Settings section. Changing to the LUT number automatically changes the Mode to LUT.
Use the Logic Pins section to toggle the
G
includes the following:
RSTB: clear the check box to bring the ADMV8052 RST pin low, which holds the chip in reset. Select the check box again to
bring the chip out of reset.
SFL: select the check box to bring the ADMV8052 SFL pin high, which places the chip in SFL mode. This action also toggles the
on-board ADG749BKSZ
connected to the
CSB_AUX: this pin is only available in SFL mode. Selecting the check box brings the CSB_AUX pin high, which advances the
internal state machine pointer to the next LUT. If an external waveform generator is connected to the CSB_EXT port on the
ADMV8052-EVALZ, the CSB_AUX pin has no effect, and the CSB_EXT port takes precedence.
H Use the Click to Enable Auto Apply button to toggle the ADMV8052 Board plug-in Auto Apply feature. This feature is useful
for quickly enabling auto apply so that any change made to the chip settings are automatically sent to the ADMV8052-EVALZ.
Once the button is clicked, the Click to Disable Auto Apply button appears.
K Click Proceed to Memory Map to open the ADMV8052 Memory Map (see Figure 8).
J1 All changes, except those made within the CONFIGURATION section, do not take effect until clicking Apply Changes. If Auto
Apply is highlighted in the ADMV8052 Board tab (see Figure 5), the Apply Changes feature continuously runs every few seconds,
and users do not have to click Apply Changes to apply or read back the block diagram settings.
J2 To read back all of the SPI registers of the chip, click Read All.
J3 Click Reset Chip to reset the chip.
J4 Click Diff to show registers that are different on the chip.
J5 Click Software Defaults to restore the software defaults to the chip, and then click Apply Changes. The software defaults for
the ADMV8052 are for all registers to be zero, except for Register 0x011, which is set to 0x7F, and the interpolation coefficients
in Register 0x300 to Register 0x32F.
J6 Click Memory Map Side-By-Side to enable the side by side memory map view.
L Click Interpolation Values to open the subdiagram for displaying and editing the interpolation coefficients (see Figure 9). The
interpolation coefficients can be changed to calibrate the center frequency and/or change the desired operating bandwidth for
each filter band. Refer to the ADMV8052 data sheet for guidance on editing the interpolation coefficients.
SDP-S logic pins, which are connected to the logic pins on the ADMV8052 chip. This section
switch connected to the ADMV8052 CS pin (see Figure 11). While in SFL mode, the ADMV8052 CS pin is
SDP-S logic pin, CSB_AUX, and normal SPI transactions are disallowed.
