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-AUT device with default drive strength setting, the typical rise/fall time is 1 ns 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 2.6 ns when the output load increases to 45 pF. One can choose to speed up the rise/fall time to 1.83ns by then increasing the drive strength setting on the LPO-AUT. + Ability to drive large capacitive loads while maintaining full swing with sharp edge rates. The LPO-AUT can support up to 60 pF or higher in maximum capacitive loads with drive strength settings.

EMI REDUCTION BY SLOWING RISE/FALL TIME (SoftLevel FUNCTION) LPO-AUT DRIVE STRENGTH SELECTION Figure 6 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. Select the table that matches the LPO-AUT nominal supply voltage (1.8V, 2.5V, 2.8V, 3.0V, 3.3V). 2. Select the capacitive load column that matches the application requirement (5 pF to 60 pF) 3. Under the capacitive load column, select the desired rise/fall times. FIGURE 6. HARMONIC EMI REDUCTION AS A FUNCTION OF SLOWER RISE/FALL TIME (SoftLevel FUNCTION) 4.

One way to reduce this jitter is to increase rise/fall time (edge 1 5 x Trf_20/80 where Trf_20/80 is the typical value for 20%-80% rise/fall time. EXAMPLE 1 Calculate fMAX for the following condition: + VDD = 1.8V (Table 1) + Capacitive Load: 30pF + Desired Tr/f time = 3 ns (rise/fall time part number code=E) rate) of the input clock. Some chipsets would require faster rise/fall Part number for the above example: time in order to reduce their sensitivity to this type of jitter.
