The 6-VDFN Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm, a standard footprint that routes easily on two-layer boards; the exposed pad improves thermal transfer to the PCB ground plane. ## Enable/Disable function and power control","metaTitle":"DSC1121AM1-041.5000T MEMS XO – 41.5 MHz CMOS, -55 to 125°C","metaDescription":"Microchip DSC1121AM1-041.5000T: 41.5 MHz MEMS XO, CMOS output, 2.25-3.6 V supply, -55 to +125°C.
