Maximum supply current is 35 mA — this is the worst-case draw at the highest frequency and lowest supply voltage; actual consumption at 27 MHz and 3.3V is lower, but budget the 35 mA ceiling for the power tree. Housed in a 6-VDFN Exposed Pad package, measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Surface-mount — standard reflow profile for a VDFN; no special bake-out required if the reel is within the floor-life window.","metaTitle":"DSC1121AM1-027.0000 MEMS XO – 27 MHz, CMOS, -55°C to 125°C","metaDescription":"Microchip DSC1121AM1-027.0000: 27 MHz MEMS XO, CMOS output, 2.25-3.6V supply, ±50 ppm stability, -55°C to 125°C range.
