This APR figure is the total frequency deviation over the full operating envelope — supply voltage, temperature, and aging — so the system clock jitter budget starts from this ±10 ppm ceiling. Microchip lists the DSC1101DI5-018.4320T as Active. The 6-VDFN package (2.50 mm × 2.00 mm footprint, 0.90 mm seated height) suits space-constrained PCBs in industrial and telecom applications where the -40 to +85°C temperature grade is required. ## Standby power-down and CMOS drive With the standby function asserted, the oscillator draws 95 µA max — the MEMS resonator stops and the output goes high-impedance. The 35 mA max active current at 18.432 MHz is typical for a CMOS-output XO at this frequency; the CMOS rail-to-rail swing eliminates the need for a termination resistor on short traces.","metaTitle":"DSC1101DI5-018.4320T MEMS XO, 18.432 MHz, CMOS Output","metaDescription":"Microchip DSC1101DI5-018.4320T: 18.432 MHz MEMS oscillator, CMOS, 2.25-3.6 V supply, -40 to +85°C, 6-VDFN.
