The 2.25V to 3.63V supply range means the oscillator runs directly from a 2.5V or 3.3V rail without a dedicated LDO — the same BOM line serves both voltage domains. ## Package and footprint – 6-SMD no-lead Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1123CI2-020.0000 fits the standard 3.2 x 2.5 mm oscillator footprint — a drop-in replacement for quartz oscillators of the same size and pinout.","metaTitle":"DSC1123CI2-020.0000 – Microchip MEMS XO, 20 MHz, LVDS","metaDescription":"Microchip DSC1123CI2-020.0000: MEMS XO, 20 MHz, LVDS output, ±25 ppm stability, 2.25V–3.63V supply, -40°C to +85°C.
