Supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails without an external regulator. ## Frequency stability and temperature grade Rated ±50 ppm frequency stability over -20°C to 70°C, which meets the timing margin for 1 GbE, PCIe Gen 1/2, and SATA interfaces without external VCXO compensation. ## Active production – sourcing posture","metaTitle":"DSC400-0344Q0051KE1 MEMS XO – 100 MHz / 156.25 MHz HCSL LVDS","metaDescription":"Active Microchip DSC400 XO, MEMS base, ±50 ppm stability, 2.25-3.6 V, 20-VFQFN.
