It's a drop-in replacement for quartz crystal oscillators in the same footprint — no external load capacitors needed, because the MEMS resonator and drive circuit are integrated in the package. That 3 mA typical supply current at 20 MHz is low enough for battery-powered gear — think wireless sensors, portable instruments, or IoT edge nodes. ## Temperature Range and Fit for Your Environment The ±50ppm frequency stability holds over that range, which is tight enough for UART, I2C, and most MCU clocking, but not for precision RF or a high-accuracy ADC reference. ## Package and Hand-Soldering Reality The 4-SMD no-lead package measures 2.5 x 2.0 mm with a seated height of 0.9 mm — a tiny land pattern. You can hand-solder it with a fine-tip iron and flux if you're careful, but reflow is the intended assembly method. The no-lead design means the pads are on the bottom; a hot-air station or a skillet rework works well for prototypes.","metaTitle":"DSC1033DE1-020.0000 MEMS Oscillator – 20 MHz CMOS XO, Active","metaDescription":"Microchip DSC1033DE1-020.0000: 20 MHz MEMS XO, CMOS output, 3.3V, ±50ppm, standby function.
