The MEMS resonator gives faster startup and better shock/vibration tolerance than quartz — relevant for automotive and industrial applications where the board sees mechanical stress.
CMOS output interfaces directly with most MCU and FPGA clock inputs without external level translation — the 24 MHz frequency is within the standard logic family fan-out limits.
Yes, the DSC1121CM1-024.0000 carries AEC-Q100 ratings, meaning it has passed automotive-grade reliability tests including temperature cycling, ESD, and latch-up. Suitable for under-hood and chassis-domain electronics.
The DSC1121CM1-024.0000 is a MEMS-based oscillator, not quartz. It is pin-compatible with many standard 6-SMD oscillators at 24 MHz CMOS output, but verify the supply voltage range (2.25V to 3.6V) and the Enable/Disable logic level against your existing quartz part. The MEMS resonator offers better shock tolerance and faster startup — a direct swap if the footprint and electrical specs match.
The Enable/Disable pin gates the CMOS output without removing power. When disabled, the oscillator draws 22 mA max versus 35 mA max active. This is useful for power-saving modes where the clock tree is halted but the oscillator remains biased for fast restart.
