SiT3807 Standard Frequency MEMS VCXO The Smart Timing Choice TheSmartTimingChoice Programmable Drive Strength The SiT3807 can support up to 60 pF maximum capacitive loads. Refer to the Rise/Tall Time Tables to determine the The SiT3807 includes a programmable drive strength feature proper drive strength for the desired combination of output to provide a simple, flexible tool to optimize the clock rise/fall load vs. rise/fall time time for specific applications. Benefits from the programmable drive strength feature are: SiT3807 Drive Strength Selection • Improves system radiated electromagnetic interference Tables 7 through 10 define the rise/fall times for a given capac- (EMI) by slowing down the clock rise/fall time itive load and supply voltage. • Improves the downstream clock receiver’s (RX) jitter by de- creasing (speeding up) the clock rise/fall time. 1.Select the table that matches the SiT3807 nominal supply voltage (1.8V, 2.5V, 2.8V, 3.3V). • Ability to drive large capacitive loads while maintaining full swing with sharp edge rates. 2.Select the capacitive load column that matches the appli- For more detailed information about rise/fall time control and cation requirement (5 pF to 60 pF) drive strength selection, see the SiTime Application Notes 3.Under the capacitive load column, select the desired section; http://www.sitime.com/support/application-notes. rise/fall times. 4.The left-most column represents the part number code for EMI Reduction by Slowing Rise/Fall Time the corresponding drive strength.

The rise/fall times are purposes. 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, Calculating Maximum Frequency the signal is very close to near-triangular waveform. These Based on the rise and fall time data given in Tables 7 through results, for example, show that the 11th clock harmonic can be 10, the maximum frequency the oscillator can operate with reduced by 35 dB if the rise/fall edge is increased from 5% of guaranteed full swing of the output voltage over temperature the period to 45% of the period. can be calculated as follows:   trise=0.05 1 10 ttrriissee==00..115 Max Frequency=3.5 x Trf_10/90 trise=0.2 0 trise=0.25 trise=0.3 dB) -10 ttrriissee==00..345 Where Trf_10/90 is the typical rise/fall time at 10% to 90% Vdd. e ( -20 trise=0.45 d mplitu -30 Example 1 a -40 armonic --6500 C•alVcdudla t=e 3fM.3AVX (fToar bthlee 1fo0l)lowing condition: H • Capacitive Load: 30 pF -70 • Typical Tr/f time = 1.66 ns (drive strength part number code -80 1 3 5 7 9 11 = G) Harmonic number Figure 11. Harmonic EMI reduction as a Function of Part number for the above example: Slower Rise/Fall Time SiT3807AIGG2-33EH-49.152000 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 Drive strength code is inserted here. Default setting is “-” 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. Refer to the Rise/Fall Time Tables to determine the proper drive strength. 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 SiT3807 device with default drive strength setting, the typical rise/fall time is 1.15ns for 15 pF output load. The typical rise/fall time slows down to 2.72ns when the output load increases to 45 pF. One can choose to speed up the rise/fall time to 1.41ns by then increasing the drive strength setting to P on the SiT3807. Rev. 1.01 Page 6 of 11 www.sitime.com

Silicon MEMS Outperforms Quartz The Smart Timing Choice The Smart Timing Choice Best Reliability Best Electro Magnetic Susceptibility (EMS) Silicon is inherently more reliable than quartz. Unlike quartz SiTime’s oscillators in plastic packages are up to 54 times suppliers, SiTime has in-house MEMS and analog CMOS more immune to external electromagnetic fields than quartz expertise, which allows SiTime to develop the most reliable oscillators as shown in Figure 3. products. Figure 1 shows a comparison with quartz Why is SiTime Best in Class: technology. • Internal differential architecture for best common mode Why is SiTime Best in Class: noise rejection • SiTime’s MEMS resonators are vacuum sealed using an • Electrostatically driven MEMS resonator is more immune advanced EpiSeal™ process, which eliminates foreign par- to EMS ticles and improves long term aging and reliability • World-class MEMS and CMOS design expertise SiTime vs Quartz Mean Time Between Failure (Million Hours) Electro Magnetic Susceptibility (EMS) - 30 SiTime 500 B) - 40 - 39 - 40 - 42 - 43 - 45 d IDT (Fox) 38 SiTime (s - 50 r 20X Better u Epson 28 pS - 60 54SXi TBimeteter e g a - 70 - 73 TXC 16 re v A - 80 Pericom 14 - 90 0 200 400 600 Kyocera Epson TXC CW SiLabs SiTime Figure 1.
