Supply voltage spans 2.25V to 3.6V, so the same BOM line works on a 2.5V or 3.3V rail — no extra regulator needed. The ±25 ppm frequency stability covers temperature, supply, and ageing combined, which is tight enough for most 1000BASE-T Ethernet and PCIe Gen 1/2/3 reference clock jitter budgets without stepping up to a TCXO. ## Standby power-down for intermittent duty The 42 mA max active draw is typical for a 100 MHz HCSL oscillator; the differential output stage accounts for most of it, so the current is fairly independent of the load capacitance.","metaTitle":"DSC1104CI2-100.0000 MEMS XO, 100 MHz HCSL, -40 to 85°C","metaDescription":"Microchip DSC1104CI2-100.0000: 100 MHz HCSL output, ±25 ppm stability, 2.25-3.6V supply, industrial temp.
