It delivers a CMOS output from a 1.71 V to 3.63 V supply, drawing 1.3 mA typical at 40 MHz — the wide voltage range lets it run directly off a 1.8 V, 2.5 V, or 3.3 V rail without an extra LDO. The -20°C to +70°C temperature range is commercial grade, so while the part is automotive-qualified, it is not rated for the full -40°C to +125°C under-hood band — it fits cabin or infotainment domains where the ambient stays above -20°C.
For new designs, a different oscillator from the DSC60XX family or a quartz-based XO with the same 40 MHz, CMOS, 4-SMD footprint is the migration path, but a board-level re-spin may be needed to match the supply voltage and enable/disable function.
For a 40 MHz clock, ±50 ppm equals ±2 kHz of jitter at the output; most MCU and FPGA clock trees tolerate this without issue, but a precision ADC or SerDes reference may need tighter stability. The 4-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. This is the standard 3.2 x 2.5 mm oscillator footprint — it fits the same land pattern as many quartz XOs, so a PCB already laid out for a 3.2 x 2.5 mm can accept this MEMS part without layout changes.
