The ±10 ppm absolute pull range (APR) holds the output frequency tighter than many quartz-based XOs; for a 72 MHz serial link, that translates to lower bit-error rate over temperature and voltage. Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator occupies minimal PCB area — suitable for space-constrained designs like IoT modules or compact industrial sensors. Surface-mount assembly with a standard 6-pin VDFN footprint; the enable/disable function is on a dedicated pin, so no external pull-up or pull-down resistor is needed for the output-enable logic.","metaTitle":"DSC1121DL5-072.0000 MEMS Oscillator 72 MHz CMOS - Microchip","metaDescription":"Active-production MEMS XO, 72 MHz CMOS output, ±10 ppm APR, -40°C to 105°C, 2.5x2.0 mm VDFN-6.
