SYNTHESIZER CONFIGURATION AND LO OPERATION
b. If in the PIN mode, do this by moving TX_ENABLE or RX_ENABLE to the low state.
3. Once in the PRIMED state, move the channel state to the calibrated state by calling adi_adrv9001_Radio_Channel_ToCalibrated().
4. Once the device is in the calibrated state, set the LO frequency by calling adi_adrv9001_Radio_Carrier_Configure(). Note that it is
recommended to run a minimum set of calibrations after changing the LO frequency by a significant step as described in the
Initial Calibrations Through TES
5. Lastly, bring the device back to the RF_ENABLED state. First bring it back to PRIMED, then to RF_ENABLED, calling the same functions
above but in reverse order.
For more details, see the API Initialization Sequence
There is no specific control over the CLK_PLL. The CLK_PLL is configured at initialization.
Note that when changing the LO, make sure all channels that utilize the LO are configured. For example, if Tx1 and Rx1 are using LO1, and
there is a need to change LO1, configure both Tx1 and Rx1. If all channels (Tx1, Tx2, Rx1, and Rx2) are using the same LO, and there is a
need to change the LO, configure all channels (Tx1, Rx2, Rx1, and Rx2).
Loop Filter Configuration
The default loop filter bandwidth for RF PLL is 300 kHz, as discussed in the
chip initialization state based on the specified DEV_CLK_IN frequency and LO phase noise requirements. The ADRV9001 TES has the RF PLL
loop filter bandwidth configuration interface to tune and achieve the best phase noise in the system.
