Why a MEMS oscillator instead of quartz
This DSC1001CI5-150.0000 uses a MEMS resonator rather than a quartz crystal — the base resonator is silicon, not quartz, which means it survives higher shock and vibration levels without the frequency jump that can plague quartz oscillators in automotive or industrial environments.
150 MHz CMOS clock with standby control
Output is 150 MHz CMOS, which directly drives the clock input of most FPGAs, MCUs, and SoCs without needing an external level translator. The standby (power-down) function drops supply current to 15 µA when the enable pin is pulled low — useful for battery-backed systems that sleep between wake cycles.
Automotive-grade qualification and temperature range
That covers under-hood and cabin electronics where a standard commercial oscillator might drift or fail early.
