2 / 17 page ![]() SiT8924B Automotive AEC-Q100 Oscillator Rev. 1.5 Page 2 of 17 www.sitime.com Table 2. Pin Description Pin Symbol Functionality 1 Output Enable Output Enable H [1]: specified frequency output L: output is high impedance. Only output driver is disabled. No Con- nect No Connect Any voltage between 0 and Vdd or Open [1]: Specified frequency output. Pin 1 has no function. 2 GND Power Electrical ground [2] 3 OUT Output Oscillator output 4 VDD Power Power supply voltage [2] Top View 1 4 OE/NC VDD 3 2 GND OUT Figure 1. Pin Assignments Notes: 1. In OE mode, a pull-up resistor of 10k or le s s is re comme nde d if pin 1 option. 2. A capacitor of value 0.1 µF or higher between Vdd and GND is required. Table 3. Absolute Maximum Limits Attempted operation outside the absolute maximum ratings may cause permanent damage to the part. Actual performance of the IC is only guaranteed within the operational specifications, not at absolute maximum ratings. Parameter Min. Max. Unit Storage Temperature -65 150 °C Vdd -0.5 4 V Electrostatic Discharge – 2000 V Soldering Temperature (follow standard Pb free soldering guidelines) – 260 °C Junction Temperature [3] – 150 °C Note: 3. Exceeding this temperature for extended period of time may damage the device. Table 4.
