PROGRAMMABLE DRIVE STRENGTH
The WTLPO-AUT includes a programmable drive strength named
SoftLevel feature to provide a simple, flexible tool to optimize the
clock rise/fall time for specific applications. 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 WTLPO-AUT device with default drive strength setting,
the typical rise/fall time is 0.46 ns for 5 pF output load. The typical
slowing down the clock rise/fall time
+ Improves the downstream clock receiver’s (RX) jitter by decreasing (speeding up) the clock rise/fall time.
rise/fall time slows down to 1 ns when the output load increases to
15 pF. One can choose to speed up the rise/fall time to 0.72 ns by
then increasing the drive strength setting on the WTLPO-AUT.
+ Ability to drive large capacitive loads while maintaining full swing
with sharp edge rates.
The WTLPO-AUT can support up to 30 pF in maximum capacitive loads
with up to 3 additional drive strength settings. Refer to the Rise/Tall
For more detailed information about rise/fall time control and drive
strength selection, please contacts the application engineers of Pe-
Time Tables (Table 1 to 5) to determine the proper drive strength for
the desired combination of output load vs. rise/fall time.

EMI REDUCTION BY SLOWING RISE/FALL TIME (SoftLevel FUNCTION)
WTLPO-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

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 WTLPO-AUT nominal
supply voltage (1.8V, 2.5V, 2.8V, 3.0V, 3.3V).

PIN 1 CONFIGURATION OPTIONS (OE or NC)
Pin 1 of the WTLPO-AUT can be factory-programmed to support two
modes: Output enable (OE) or No Connect (NC).
FIGURE 7. STARTUP WAVEFORM vs. VDD
OUTPUT ENABLE (OE) MODE
In the OE mode, applying logic Low to the OE pin only disables the
output driver and puts it in Hi-Z mode. The core of the device
continues to operate normally. Power consumption is reduced due
to the inactivity of the output. When the OE pin is pulled High, the
output is typically enabled in <1µs.
NO CONNECT (NC) MODE
In the NC mode, the device always operates in its normal mode
and output the specified frequency regardless of the logic level on
pin 1. Table 6 below summarizes the key relevant parameters in the
operation of the device in OE or NC mode.

OUTPUT ON STARTUP AND RESUME
The WTLPO-AUT comes with gated output. Its clock output is
accurate to the rated frequency stability within the first pulse from
initial device startup or when the output driver is enabled.
In addition, the WTLPO-AUT supports “no runt” pulses and “no
glitch” output during startup or when the device output
driver is
enabled as shown in the waveform captures in Figure 7 and Figure
8.
