Frequency stability is ±25 ppm across the full temperature and voltage range — tight enough for 1000BASE-T Ethernet and PCIe Gen 1/2/3 reference clock jitter budgets. For applications requiring ±20 ppm or better, a different stability grade in the DSC1104 family would be needed. ## Standby power-down and package footprint The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm, fitting tight board stacks in handheld or embedded designs.","metaTitle":"DSC1104CI2-027.0000 MEMS XO 27 MHz HCSL - Microchip","metaDescription":"DSC1104CI2-027.0000: 27 MHz MEMS XO, HCSL output, ±25 ppm stability, -40°C to 85°C, 2.25V-3.6V supply.
