This device can be programmed for any frequency between 1 Hz and 462.5 kHz. The silicon MEMS technology makes it possible to produce the world's smallest, programmable reference clock in a chip-scale package. The SiT1569 oscillator is Factory trimmed to 32.768 kHz at room temperature. The result is a very accurate oscillator at room temperature and over temperature. Unlike quartz crystals that have a classic tuning fork parabola temperature curve with a 25°C turnover point with a 0.04 to 0.06 ppm/°C2 temperature coefficient (TCF), the SiT1569 temperature coefficient is calibrated at room temperature and corrected over temperature with an active temperature correction circuit. The result is 100 ms. Shorter gate times may lead to inaccurate measurements.

Permanent damage or long term reliability issues may occur. 2) Applying board-level underfill and overmold is acceptable and will not impact the reliability of the device. 3) Reflow profile, per JESD22-A113D. Rev 1.2 Page 5 of 7 polymer top-coat. If the SiT1569 will see intense light, especially in the 1.0-1.2µm IR spectrum, we recommend a protective “glob-top” epoxy or other cover to keep the light from negatively impacting the frequency stability. 5) For additional manufacturing guidelines and marking/tape-reel instructions, refer to SiTime Manufacturing Notes. www.sitime.com SiT1569 µPower, Ultra-Small 1 Hz – 462.5 kHz ±50 ppm Oscillator Ordering Information SiT1569AC -J3-33E-0000.000000Q Packaging Part Family “S”: 8 mm Tape & Reel, 10 ku reel “Q”: 8 mm Tape & Reel, 5 ku reel “D”: 8 mm Tape & Reel, 3 ku reel “E”: 8 mm Tape & Reel, 1 ku reel Samples in cut Tape “SiT1569” Revision Letter “A” is the revision Output Frequency Continuous frequency options from 1 Hz to 462.5 kHz Temperature Range “C”: Commercial, -20 to 70ºC “I”: Industrial, -40 to 85ºC Enter your desired frequency as shown below: 0462.500000 = 462.5 kHz 0100.000000 = 100.0 kHz 0010.000000 = 10.0 kHz 0001.000000 = 1.0 kHz 0000.100000 = 100.0 Hz 0000.010000 = 10.0 Hz 0000.001000 = 1.0 Hz 0000.001100 = 1.10 Hz 0000.005123 = 5.123 Hz Package Size “J”: 1.5 x 0.8 mm CSP Frequency Stability “3”: ±50 ppm Supply Voltage (Vdd): 18E: 1.8 V ±10% 25E: 2.5 V ±10% 30E: 3.0 V ±10% 33E: 3.3 V ±10% For applications that require operation over wide range, enter the option that corresponds to the highest supply voltage.
