The MEMS resonator inherently withstands higher shock and vibration than quartz — a practical advantage for engine-bay or chassis-mounted modules that see 50 g impacts during assembly or road debris. ## ±50 ppm stability and wide supply tolerance The 2.25V to 3.6V supply range lets the oscillator share a 2.5V or 3.3V rail with the MCU or FPGA, eliminating a dedicated LDO. ## Active lifecycle and AEC-Q100 grade This is the same qualification level used for engine-control and transmission modules. ## 6-SMD package and board layout Housed in a 6-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The small footprint suits space-constrained designs like ADAS cameras or telematics modules.","metaTitle":"DSC1121DM1-050.0000T MEMS Oscillator","metaDescription":"Microchip DSC1121DM1-050.0000T MEMS XO, 50 MHz CMOS output, ±50 ppm stability, -55°C to 125°C, AEC-Q100.
