Functional Description The Si50x series oscillator family includes four base devices. All devices are configurable according to the Section 5. "Ordering Guide". The four devices each support a single clock output frequency at any one time and are segmented according to the number of clock frequencies they store in on-chip memory. The Si501 supports a single stored frequency, enabled with the OE functionality. The Si502 stores two frequencies that can be selected with FS and enabled/disabled with OE functionality. The Si503 stores four frequencies, selected with FS functionality. The Si503 does not support OE functionality. The Si501/2/3 are covered in this data sheet. The Si504 is a programmable oscillator, controlled through a single pin interface (C1D). It is covered in its own Si504 data sheet available at www.siliconlabs.com/cmems. All devices in the Si50x CMEMS series employ a cost-optimized, power-efficient, digital FLL architecture to produce a highly accurate and stable output clock from a passively compensated MEMS resonator reference frequency. The architecture uses the MEMS resonator as its reference frequency along with a divided signal from an on-chip, digitally-controlled VCO to drive a frequency comparator for the FLL's digital loop filter. The digital loop filter accumulates and further processes the frequency error values to produce the target output frequency. The architecture also uses a high-resolution, low-noise temperature sensor and temperature compensation algorithm to offset any temperature drift of the passively compensated MEMS resonator. Each device is calibrated for temperature and MEMS-resonator frequency pairs and derives a device-specific compensation polynomial. As the temperature changes, this compensation circuitry offsets any frequency drift. This tightly coupled system is extremely accurate and fast because the MEMS resonator and CMOS compensation circuitry are in a single, monolithic chip, and, therefore, separated by a few microns. The complete system process occurs many thousands of times per second, providing excellent frequency accuracy and stability across temperature changes, including any fast temperature transients. The oscillator also supports a low-power version that reduces the sampling cycle to a longer period, reducing power consumption for applications that can tolerate relaxed jitter specifications of approximately 1 ps RMS to reduce power by approximately 2-3 mA. See Table 1 for exact specifications. 3.1. OE Enable and Disable States The Si50x CMEMS series supports four operational output states via the FS/OE configuration pin. If enabled, the Si50x is in Run mode, the clock is output and power is as specified in Table 1. The disable modes are Stop, Sleep, and Doze. Each of these states has a different power consumption profile as specified in Table 1. 3.1.1. Stop Mode The Si50x output in Stop mode is high-impedance, also known as High-Z (Hi-Z) or Tri-State. Stop mode disables the output driver, but the digital core and MEMS resonator remain enabled for fast transition to Run mode. The output is stopped and held at High-Z after completing the last cycle glitch-free. No other power saving measure is taken in Stop mode. 12 Rev. 1.0 Si501/2/3 3.1.2. Doze Mode The Si50x output in Doze mode is high-impedance, also known as High-Z (Hi-Z) or Tri-State. Doze mode disables the output driver, the VCO, and the MEMS resonator, but the digital core remains enabled. The output is stopped and is held at High-Z after completing the last cycle glitch-free. 3.1.3. Sleep Mode The Si50x output in Sleep mode is high-impedance, also known as High-Z (Hi-Z) or Tri-State. Sleep mode disables power to all circuitry except for low-leakage circuitry that retains the last device configuration. The output is stopped and is held at High-Z after completing the last cycle glitch-free. 3.2. Output Rise and Fall Settings The Si50x clock output is programmable. This enables reduction of electromagnetic interference (EMI) radiation from the clock output. The amount of EMI reduction is dependent on the output frequency, the harmonic of interest, and the board layout. Lab results using a 50 MHz FOUT and changing the clock tRise/tFall time from 0.7 ns to 8 ns show up to 14 dB of EMI reduction. The tRise/tFall feature also allows the Si50x to match competing devices' rise and fall times. Crystal oscillator tRise/tFall behavior is largely dependent on the supply voltage. In crystal-based oscillators, a higher supply voltage will generally drive a more rapid tRise/tFall time. The Si50x configuration options allow the user to match the tRise/tFall to the supply voltage. The Si50x also provides a specified tRise/tFall with a given supply voltage and a 50 trace impedance. See Table 3 for Si50x tRise/tFall specifications. 4. Pin Descriptions FS/OE 1 GND 2 4 VDD 3 CLK Figure 9. Si501/2/3 Table 11. Pin Description Pin Name Function 1 FS/OE FS=Frequency Select.
