ADMV4630 BLOCK DIAGRAM AND FUNCTIONS
analog.com Rev. A | 7 of 11
Table 1. ADMV4630 Block Diagram Label Functions (See Figure 7 )
Label Function
H Click the AGPIO switch (represented by Label H) to set the SEL_AGPIO bit (Bit 3, Register 0x301). When the AGPIO switch is set to the right, the SEL_AGPIO
bit is disabled and the AGPIO pin is used as data output. When the AGPIO switch is set to the left, the SEL_AGPIO bit is enabled and the AGPIO pin is used
as external data input. See the ADMV4630 data sheet for further details.
I ADC blocks. Click Read from ADC to read back ADC values. See the ADMV4630 data sheet for further details.
J Click the AMUX switch (represented by Label J) to set the SEL_AMUX bit (Bit[2:0], Register 0x301). There are three options for the AMUX, AGPIO, and power
detector and temperature sensor (PTAT). See the ADMV4630 data sheet for further details.
K Enter a value in the REF IN text box to set the reference frequency.
L1 Use the INT scroll to choose a value, or enter a value in the text box to set the 16-bit integer value (Register 0x200, Register 0x201) of the synthesizer. The
VCO Frequency (Label L2) value is calculated based on the INT value. Alternatively, change the VCO Frequency to calculate the INT value.
L2 Enter a value in the VCO Frequency text box to set the VCO frequency. The INT value is calculated based on the VCO Frequency value. Alternatively,
change the INT value to calculate the VCO Frequency value.
M Click POWER DETECTOR to set the DET_BIAS_CONTROL bit (Bit 5, Register 0x100). When POWER DETECTOR is highlighted, the DET_BIAS_CONTROL
bit is enabled. When POWER DETECTOR is not highlighted, the DET_BIAS_CONTROL bit is disabled.
N1 Click the Doubler switch to set the DOUBLER_EN bit (Bit 3, Register 0x20E). When the Doubler Enable switch is highlighted, the DOUBLER_EN bit is
enabled. When the Doubler Enable switch is not highlighted, the DOUBLER_EN bit is disabled.
N2 Use the R Divider scroll to choose a value, or enter a value in the text box to change the reference divider value (Bit[4:0], Register 0x20C).
N3 Click Divide-by-2 to set the RDIV2_EN bit (Bit 0, Register 0x20E). When Divide-by-2 is highlighted, the RDIV2_EN bit is enabled. When Divide-by-2 is not
highlighted, the RDIV2_EN bit is disabled.
O Click Initialization & Optimization to initialize and lock the PLL.
P Use the DSA scroll to choose a value, or enter a value to set the SEL_DSA_ATTEN bit (Bit[4:0], Register 0x300).
Q Click Proceed to Memory Map to open the ADMV4630 memory map (see Figure 8 ).
