ARBITRARY SAMPLE RATE

With a programmable frequency range of both HP CLK PLL and LP CLK PLL (as mentioned previously), the ADRV9001 supports the arbitrary
sample rate (ASR) mode, which provides great flexibility to configure the desired sample rates in the applications. The ASR mode supports an
almost continuous range of rates up to 61.44 MHz, with a list of dead zones mainly due to the limitations in the decimation/interpolation rate
supported in the datapath. Table 42
