Hi,Currently my lock time is close to 8.5ms (ADIsimPLL reports 6.1ms for my loop filter config). I would like to improve this and expecting to bring it down. ADF5355 datasheet mentions that "Much faster lock times than those detailed in this data sheet are possible; contact Analog Devices for more information". Any information about improving the lock times would be much appreciated.
Faster lock times can be achieved with bypassing the autocalibration and selecting the VCO core, band and bias manually. This application requires one time look up table creation for the desired frequencies and using these in following power-up cycles. AN-1353 provides the details of VCO calibration bypass.
Hi,When i use a python program to write to the 'sys/bus/iio/devices/iio:device3/out_altvoltage0_frequency' file to set the LO frequency, it takes 8.5 ms to return from the write. is the lock time of the ADF5355 included in this 8.5ms ??
