It comes in a 2.50 mm × 2.00 mm 4-SMD no-lead package — the same footprint as many quartz oscillators, so it drops onto a standard oscillator land pattern without a board spin. ## Standby mode and the 1 µA sleep current A dedicated standby (power-down) pin pulls the oscillator into a disabled state where the supply current drops to 1 µA max. This is the key feature for battery-operated or duty-cycled systems: the oscillator's own draw during sleep is negligible compared to the rest of the BOM, so a sensor node that wakes once a minute to take a reading and transmit can run months on a coin cell. Microchip lists the DSC1033DI1-048.0000 as Obsolete. No pin-compatible replacement from Microchip's current DSC1033 family has been formally designated as a drop-in, so a board-level change may be needed if a second source is required.","metaTitle":"DSC1033DI1-048.0000 MEMS Oscillator 48 MHz CMOS - Microchip","metaDescription":"DSC1033DI1-048.0000 XO (Standard) MEMS oscillator, 48 MHz CMOS output, ±50 ppm stability, -40°C to 85°C.
