The 2.50mm x 2.00mm 4-SMD no-lead package (0.90mm seated height) fits tight PCB layouts and is hand-solderable with a fine-tip iron — no reflow oven required for prototyping. Operates from a single 1.8V to 3.3V supply, covering the three most common digital logic rails without an external regulator — the CMOS output swings rail-to-rail, so it drives MCU clock inputs directly. Maximum active current is 6.3 mA; the Standby (Power Down) function drops supply current to 15 µA max, making it suitable for battery-powered systems that sleep between wake cycles — a logic-level signal on the enable pin shuts down the oscillator.","metaTitle":"DSC1001DE1-018.4320T MEMS XO – 18.432 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001DE1-018.4320T MEMS oscillator: 18.432 MHz, CMOS output, 1.8V-3.3V supply, AEC-Q100, 2.5x2.0mm SMD.
