FREQUENCY HOPPING
Figure 128. Padded Data Method for Tx Only Hopping with Short Propagation Delay
Figure 129 shows an alternative to hold off from the transmission until t prior to the analog front end is enabled. Here, the FPGA

ORx Operation
The ADRV9001 supports ORx operation in the FH modes. ORx in FH works like the normal TDD mode. During the actual Tx frame, set the
ORx enable signal (assign to a DGPIO pin) high to enable ORx. Before the end of the Tx frame, set ORx low to disable ORx. Note this
is required regardless of whether the next frame is Tx or Rx. Take the ORx setup and bring down time into consideration, as well as the
