Supply voltage spans 2.25V to 3.6V, so the same part works on 2.5V and 3.3V rails without a separate LDO — one BOM line covers mixed-voltage designs. ## Enable/disable function and power-down control Maximum supply current is 22 mA when enabled; the disable function cuts that to near zero, which is useful for battery-powered equipment or thermal management in dense boards. ## 6-SMD no-lead package — board layout fit Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many 5.0 x 3.2 mm oscillator pads.","metaTitle":"DSC1121BM1-026.0000T MEMS Oscillator – 26 MHz, CMOS","metaDescription":"Microchip DSC1121BM1-026.0000T – 26 MHz XO, CMOS output, ±50 ppm stability, 2.25V–3.6V supply, -55°C to 125°C.
