The disable current is still non-trivial — plan a load switch if the oscillator must be powered down to single-digit microamps during system sleep. ## Package, footprint, and layout considerations The 6-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. This is a standard 3.2 x 2.5 mm oscillator footprint — the same land pattern used by many quartz and MEMS XOs — so a layout designed for a SiTime or Epson part of the same size accepts this DSC1121 without a board spin.","metaTitle":"DSC1121CM1-027.0000 – Microchip MEMS XO, 27 MHz, CMOS","metaDescription":"DSC1121CM1-027.0000: Microchip DSC1121 series MEMS XO, 27 MHz CMOS output, AEC-Q100 qualified, -55°C to 125°C, 2.25V–3.6V supply.
