Hi Suraj, 
 The speed of Tramp for each application is different and I don't have a minimum time available. T_ramp is dependent on a number of factors including phase / frequency settling time of loop, number of steps, delta between steps, pfd frequency, SPI write time. You'll can to investigate this using one of our evaluation kits.
