The low profile suits space-constrained boards in set-top boxes, routers, and industrial controllers. Supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails without an external regulator.","metaTitle":"DSC1104BI1-027.0000T Microchip MEMS XO, 27 MHz, HCSL","metaDescription":"DSC1104BI1-027.0000T: Microchip Technology MEMS XO, 27 MHz, HCSL output, ±50 ppm stability, -40°C to 85°C, 6-VDFN.
