The SiT8008 includes a programmable drive strength 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: The SiT8008 can support up to 60 pF or higher in maximum capacitive loads with up to 3 additional drive strength settings. Refer to the Rise/Tall Time Tables to determine the proper drive strength for the desired combination of output load vs. rise/fall time - Improves system radiated electromagnetic interference (EMI) by slowing down the clock rise/fall time - Improves the downstream clock receiver’s (RX) jitter by decreasing (speeding up) the clock rise/fall time. ## **SiT8008 Drive Strength Selection** Tables 1 through 5 define the rise/fall time for a given capacitive load and supply voltage. - Ability to drive large capacitive loads while maintaining full swing with sharp edge rates. For more detailed information about rise/fall time control and drive strength selection, see the SiTime Applications Note section; http://www.sitime.com/support/application-notes. 1. Select the table that matches the SiT8008 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) ## **EMI Reduction by Slowing Rise/Fall Time** 3. Under the capacitive load column, select the desired rise/fall times. Figure 13 shows the harmonic power reduction as the rise/fall times are increased (slowed down). The rise/fall times are expressed as a 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. 4. The left-most column represents the part number code for the corresponding drive strength. 5. Add the drive strength code to the part number for ordering purposes. ## **Calculating Maximum Frequency** Based on the rise and fall time data given in Tables 1 through 4, the maximum frequency the oscillator can operate with guaranteed full swing of the output voltage over temperature as follows: **==> picture [396 x 134] intentionally omitted <==** **----- Start of picture text -----**

Calculate fMAXMAX for the following condition: - Desired Tr/f time = 3 ns (rise/fall time part number code = E) **Figure 13. Harmonic EMI reduction as a Function of Slower Rise/Fall Time** ## **Jitter Reduction with Faster Rise/Fall Time** Power supply noise can be a source of jitter for the downstream chipset. 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. The SiT8008 provides up to 3 additional high drive strength settings for very fast rise/fall time. Refer to the Rise/Fall Time Tables to determine the proper drive strength. Part number for the above example: SiT8008AI **E** 12-18E-25.000000T Drive strength code is inserted here. Default setting is “-” ## **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 example, for a 3.3V SiT8008 device with default drive strength setting, the typical rise/fall time is 1ns for 15 pF output load. The typical rise/fall time slows down to 2.6ns when the output load increases to 45 pF.

The field programmable devices (FP devices) are available for all five standard SiT8008 package sizes and can be configured to one’s exact specification using the Time Machine II, an USB powered MEMS oscillator programmer. For more information regarding SiTime’s field programmable solutions, visit http://www.sitime.com/time-machine and http://www.sitime.com/fp-devices. SiT8008 is typically factory-programmed per customer ordering codes for volume delivery. ## **Customizable Features of the SiT8008 FP Devices Include** - Any frequency between 1 – 110 MHz - Three frequency stability options, ±20 PPM, ±25 PPM, ±50 PPM - Two operating temperatures, -20 to 70°C or -40 to 85°C - Five supply voltage options, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V and 2.25 to 3.65V continuous - Output drive strength **Page 7 of 11** **Rev. 1.11** **www.sitime.com** **SiT8008 Low Power Programmable Oscillator**  ~~a~~ The Smart Timing ChoiceThe Smart Timing Choice ## **Dimensions and Patterns** **==> picture [549 x 613] intentionally omitted <==** **----- Start of picture text -----**

Unlike quartz suppliers, SiTime has in-house MEMS and analog CMOS expertise, which allows SiTime to develop the most reliable products. Figure 1 shows a comparison with quartz technology. ## **Why is SiTime Best in Class:** - SiTime’s MEMS resonators are vacuum sealed using an advanced Epi-Seal™ process, which eliminates foreign particles and improves long term aging and reliability ## **Best Electro Magnetic Susceptibility (EMS)** SiTime’s oscillators in plastic packages are up to 54 times more immune to external electromagnetic fields than quartz oscillators as shown in Figure 3. ## **Why is SiTime Best in Class:** - Internal differential architecture for best common mode noise rejection - Electrostatically driven MEMS resonator is more immune to EMS - World-class MEMS and CMOS design expertise **==> picture [223 x 145] intentionally omitted <==** **----- Start of picture text -----**
