Rated at ±10 ppm frequency stability, the DSC1121CE5-050.0000 holds the 50 MHz output tight enough for a 100BASE-TX PHY or a Cortex-M PLL without extra margin in the timing budget. It is not rated for engine-bay or outdoor telecom enclosures where ambient exceeds 70°C — confirm the thermal profile before layout. ## Package and board-mounting note Housed in a 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm, the DSC1121CE5-050.0000 shares the footprint common to many MEMS oscillators.","metaTitle":"DSC1121CE5-050.0000 – Microchip MEMS XO, 50 MHz, CMOS","metaDescription":"DSC1121CE5-050.0000: MEMS XO, 50 MHz, CMOS output, ±10 ppm stability, AEC-Q100 qualified.
