The Enable/Disable function allows the output to be tri-stated for power savings or test mode isolation. ## Industrial temperature grade and MEMS reliability The MEMS base resonator provides inherent shock and vibration tolerance compared to quartz, reducing the risk of startup failures in high-G environments. Listed as Active by Microchip Technology, the DSC1121CL5-040.0000T remains in ongoing production and is suitable for new designs and volume BOMs. Sourced through independent distribution; quoted to order against the BOM quantity. ## 6-VDFN package and board layout Surface-mount assembly on a 2-layer board is straightforward; the small outline saves space in dense clock trees.","metaTitle":"DSC1121CL5-040.0000T MEMS Oscillator – 40 MHz, CMOS, Active","metaDescription":"Microchip DSC1121CL5-040.0000T XO (Standard) MEMS oscillator, 40 MHz CMOS output, ±10ppm stability, -40°C to 105°C, 6-VDFN.
