Microchip DSA1001/3/4 1.8V-3.3V Low-Power Precision CMOS Oscillators for Automotive Features • Automotive AEC-Q100 Qualified • Frequency Range: 1 MHz to 150 MHz • Exceptional Stability over Temperature - ±20 ppm, ±25 ppm, ±50 ppm • Operating Voltage - 1.7 to 3.6V • Operating Temperature Range - Automotive Grade 2: -40°C to 105°C - Automotive Grade 3: -40°C to 85°C • Low Operating and Standby Current - 6 mA Operating (1 MHz) - 15 |jA Standby (Max.) • Ultra Miniature Footprint - 2.5 mm x 2.0 mm x 0.85 mm - 3.2 mm x 2.5 mm x 0.85 mm - 5.0 mm x 3.2 mm x 0.85 mm • MIL-STD 883 Shock and Vibration Resistant General Description The DSA1001/3/4 is a silicon MEMS based CMOS family of oscillators that offers excellent jitter and stability performance over a wide range of supply voltages and temperatures. The device operates from 1 MHz to 150 MHz with supply voltages between 1.8 to 3.3 volts and temperature ranges up to -40°C to 105°C. The DSA1001/3/4 incorporate an all silicon resonator that is extremely robust and nearly immune to stress related fractures, common to crystal based oscillators. Without sacrificing the performance and stability required of today's systems, a crystal-less design allows for a higher level of reliability, making the DSA1001/3/4 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal based systems. Available in industry standard packages, the DSA1001/3/4 can be “dropped-in” to the same PCB footprint as standard crystal oscillators. • Pb Free, RoHS, Reach SVHC Compliant Applications • Automotive Infotainment • Automotive ADAS • Automotive Camera Module Benefits • Replace High Temperature Crystals and Quartz Oscillators • Pin for Pin “Drop-In” Replacement for Industry Standard Oscillators • Semiconductor Level Reliability, Significantly Higher than Quartz • Longer Battery Life/Reduced Power Consumption • Compact Plastic Package • Cost Effective The DSA1003 and DSA1004 have the same functionality and performance as the DSA1001, but feature higher output drives of 25 pF and 40 pF, respectively.

t Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended periods may affect device reliability.

TABLE 1-1: ELECTRICAL CHARACTERISTICS (CONTINUED) Electrical Characteristics: Vdd = 1.8 to 3.3V; TA = +85°C unless otherwise specified. Note 1: tSU is time to stable output frequency after Vdd is applied. tSU and tEN (after EN is asserted) are identical values. 2: Measured over 50k clock cycles.

TABLE 1-1: ELECTRICAL CHARACTERISTICS (CONTINUED)

Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction to air (i.e., TA, Tj, 9jA). Exceeding the maximum allowable power dissipation will cause the device operating junction temperature to exceed the maximum +150°C rating. Sustained junction temperatures above +150°C can impact the device reliability.
