The MEMS resonator replaces a quartz crystal, offering inherent shock and vibration tolerance over a crystal oscillator in the same 5.0 mm × 3.2 mm 4-SMD no-lead footprint. ## Standby function and current profile Active draw is 3 mA typ, keeping the thermal contribution low in a sealed enclosure. Microchip lists the DSC1033BI1-035.3280 as Obsolete. No pin-compatible successor is recorded under the same order code; a board-level redesign to a current Microchip MEMS oscillator family is the migration path.","metaTitle":"DSC1033BI1-035.3280 MEMS XO 35.328 MHz CMOS Obsolete –","metaDescription":"Microchip DSC1033BI1-035.3280 MEMS XO, 35.328 MHz, CMOS output, ±50 ppm, -40°C to +85°C, 3.3V.
