The ±10 ppm absolute pull range (APR) holds the frequency across temperature and aging — tight enough for 100BASE-TX Ethernet or a USB clock without external trimming. ## MEMS vs quartz — shock tolerance and startup reliability A quartz oscillator at 33.3333 MHz in the same 6-VDFN footprint would typically offer similar stability but with higher sensitivity to mechanical stress and a longer startup time; the MEMS construction gives the DSC1121CL5 an edge in high-vibration or rapid-thermal-cycling applications. ## 6-VDFN package — board layout notes","metaTitle":"DSC1121CL5-033.3333 MEMS Oscillator 33.3333 MHz CMOS -","metaDescription":"Active MEMS XO, 33.3333 MHz CMOS output, 2.25-3.6V, -40°C to 105°C, ±10 ppm APR.
