The no-lead land pattern is straightforward for reflow; the Enable/Disable function allows the output to be tri-stated without removing supply, useful for sharing a clock line in a multi-load bus. The MEMS resonator eliminates the quartz crystal — no startup jitter or aging drift typical of crystal oscillators, and the part survives reflow profiles without frequency shift.","metaTitle":"DSC1121NI2-018.4320 MEMS XO 18.432 MHz CMOS AEC-Q100 –","metaDescription":"Microchip DSC1121NI2-018.4320: MEMS-based XO, 18.432 MHz CMOS output, ±25 ppm stability, AEC-Q100, -40°C to 85°C, 6-SMD.
