Product details

18.432 MHz MEMS XO with AEC-Q100 qualification

The DSC1121NI2-018.4320 is a MEMS-based XO (Standard) oscillator delivering a 18.432 MHz CMOS output.

6-SMD package and rework considerations

Housed in a 6-SMD no-lead package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. 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.
