No programmability: the frequency is laser-trimmed at the factory to 54 MHz and locked. The package is a 4-SMD no-lead with an exposed pad (7.00 mm × 5.00 mm, seated height 0.90 mm). Standard reflow profile for a 4-layer board with via-in-pad under the pad is fine; the MEMS die is not moisture-sensitive beyond MSL 1 typical for this class. ## Industrial temperature range and ±25 ppm stability Active current draw is 4 mA typical at 54 MHz into a CMOS load. Standby (power-down) mode drops to 1 µA max via the Standby pin — useful for battery-powered designs that sleep the oscillator between wake events. The disable pin is active-low; leave it pulled high or tied to Vdd if not used. This is a current, design-in-capable part. Confirm the full order code matches your BOM — a different suffix changes voltage, stability, or temp range.","metaTitle":"DSC1033AI2-054.0000C - 54 MHz MEMS XO, ±25 ppm","metaDescription":"DSC1033AI2-054.0000C 54 MHz MEMS oscillator from Microchip. ±25 ppm stability, 4 mA active, 1 µA standby.
