The 4 mA typical supply current (max 4 mA) keeps the thermal contribution low in a dense layout. ## Standby function for power-sensitive BOMs This is useful in battery-operated or intermittently-powered designs where the clock can be gated off between active periods, saving the 4 mA active draw when the system sleeps. Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The 0.276\" × 0.197\" footprint is a common 7×5 mm oscillator land pattern — it drops onto the same pads as many quartz XOs, so a board layout designed for a standard 7×5 mm can accept this MEMS part without a respin. This is a current-design-in part, not a last-time-buy or obsolete line. No pin-compatible second source is documented, but the DSC1033 family footprint is standard 7×5 mm, so a quartz XO with the same pinout and supply voltage can serve as a functional alternative if availability shifts.","metaTitle":"DSC1033AE1-048.0000 – 48 MHz MEMS XO, CMOS, 3.3V, Active","metaDescription":"DSC1033AE1-048.0000: 48 MHz MEMS oscillator, CMOS output, 3.3V supply, ±50 ppm stability, 4 mA typ, 1 µA standby.
