Supply voltage range is 2.25 V to 3.6 V, allowing a single oscillator to work across 2.5 V and 3.3 V rails without a separate regulator. ## 6-SMD package — board layout fit Housed in a 6-SMD, No Lead package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The 6-pin footprint is common across the DSC1124 family — the enable/disable function is on pin 1, output on pin 4, and the remaining pins are supply and ground.","metaTitle":"DSC1124AI2-100.0000T — Microchip MEMS XO, 100 MHz HCSL","metaDescription":"Microchip DSC1124AI2-100.0000T: MEMS XO, 100 MHz, HCSL output, ±25 ppm, -40°C to 85°C, 6-SMD.
