    Hi Shlomi,

    The PGA460 is only capable of bursting up to 31 pulses at frequency increments of 0.2kHz between 30-80kHz. The resolution requirement you've presented is too precise (down to the ones of Hz).

    The idea of coding is currently not supported by the PGA460 or TDC1000, and will either require a discrete implementation.

    The PGA460 can be interrupted with minimal delay between burst sets to update the driving frequency to enable back-to-back (continuous bursting) if the master controller is able to precisely keep track of the timing difference between each burst set. Does this system allow for 0.2kHz driver resolution with periodic delays as a workaround?
