Benefits from the programmable drive strength feature are: HIGH OUTPUT LOAD CAPABILITY The rise/fall time of the input clock varies as a function of the actual capacitive load the clock drives. At any given drive strength, the rise/ fall time becomes slower as the output load increases. As an examp- + Improves system radiated electromagnetic interference (EMI) by le, for a 3.3V LPO device with default drive strength setting, the typical rise/fall time is 1ns for 15 pF output load. The typical rise/fall slowing down the clock rise/fall time + Improves the downstream clock receiver’s (RX) jitter by decreasing (speeding up) the clock rise/fall time. time slows down to 1.8ns when the output load increases to 30 pF. One can choose to speed up the rise/fall time to 1.38ns by then increasing the drive strength setting on the LPO. + Ability to drive large capacitive loads while maintaining full swing with sharp edge rates. The LPO can support up to 30 pF or higher in maximum capacitive loads with up to 3 additional drive strength settings. Refer to the For more detailed information about rise/fall time control and drive strength selection, see the Petermann-Technik Applications Note Rise/Tall Time Tables to determine the proper drive strength for the desired combination of output load vs. rise/fall time. section: http://www.petermann-technik.com EMI REDUCTION BY SLOWING RISE/FALL TIME (SoftLevel FUNCTION) LPO DRIVE STRENGTH SELECTION Figure 13 shows the harmonic power reduction as the rise/fall times Tables 1 through 5 define the rise/fall time for a given capacitive load are increased (slowed down). The rise/fall times are expressed as a and supply voltage. ratio of the clock period. For the ratio of 0.05, the signal is very close to a square wave. For the ratio of 0.45, the rise/fall times are very close to near-triangular waveform. These results, for example, show that the 11th clock harmonic can be reduced by 35 dB if the rise/fall edge is increased from 5% of the period to 45% of the period. 10 Select the capacitive load column that matches the application requirement (5 pF to 30 pF) Under the capacitive load column, select the desired rise/fall times. 4. The left-most column represents the part number code for the corresponding drive strength. 5. 0 Select the table that matches the LPO nominal supply voltage (1.8V, 2.5V, 2.8V, 3.0V, 3.3V). 2. 3.

One way to reduce this jitter is to increase rise/fall time (edge rate) of the input clock. Some chipsets would require faster rise/fall time in order to reduce their sensitivity to this type of jitter.
