This means the original manufacturer has ceased production and no longer accepts orders for this part number. For existing designs that require this exact frequency, output, and package, the only sourcing channel is the independent surplus market. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here. ## What this oscillator delivers — key ratings for fit A 48 MHz clock output in CMOS logic levels from a MEMS-based resonator — the base resonator is MEMS, not quartz, which gives it better shock and vibration tolerance than a traditional crystal oscillator. The 10 mA max supply current at 48 MHz is modest for a standard XO. Includes a Standby (Power Down) function that drops the supply current to 1 µA max when the enable pin is pulled low — useful for battery-powered systems that need to gate the clock during sleep modes. Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The no-lead construction means the solder joints are hidden under the package — a hot-air rework station with a fine nozzle is the practical removal method, and the pad layout should be verified against the land pattern in the datasheet before committing the board.","metaTitle":"DSC1033CI2-048.0000 MEMS Oscillator 48MHz CMOS Obsolete","metaDescription":"Microchip DSC1033CI2-048.0000 XO (Standard) MEMS oscillator, 48 MHz CMOS output, 3.3V, ±25ppm, -40°C~85°C.
