The Enable/Disable function lets firmware gate each output independently, useful for power-sequencing or test-mode isolation without external load switches. The wide supply range (2.25 V to 3.6 V) means this oscillator works across 2.5 V and 3.3 V rails without a separate regulator, simplifying power-tree planning.","metaTitle":"DSC400-0444Q0009KI1 MEMS XO – 3× 100 MHz HCSL, Active","metaDescription":"DSC400-0444Q0009KI1: MEMS-based XO, triple 100 MHz HCSL outputs, ±50 ppm stability, -40°C to +85°C, 20-VFQFN.
