CMOS output is the standard logic level for most MCUs, FPGAs, and Ethernet PHYs — no level translation needed at the clock input. Housed in a 6-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, this oscillator fits the standard 3.2x2.5mm land pattern used by many quartz oscillators — no board layout change needed when switching from a crystal-based part.","metaTitle":"DSC1121CM1-014.7456T MEMS Oscillator","metaDescription":"Active-production MEMS XO from Microchip, 14.7456 MHz CMOS output, ±50 ppm stability, -55°C to 125°C.
