Product details

The DSC1001CC1-033.3333 is a MEMS-based standard oscillator (XO) delivering a 33.3333 MHz CMOS output — a drop-in clock source for automotive-qualified electronics that need a precise, low-jitter reference without a quartz crystal's mechanical failure modes.

Supply voltage and standby power

Operates across a 1.8V to 3.3V supply range, covering common digital rails without an extra regulator — the same oscillator can serve a 1.8V MCU core and a 3.3V peripheral bus on the same board.

Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts in automotive ECU and sensor modules.

Frequently asked questions

Does DSC1001CC1-033.3333 have a standby mode?

Yes, it includes a standby (power-down) function. When disabled, the maximum supply current drops to 15 µA, making it suitable for power-sensitive designs that need to shut down the clock tree during sleep.

How does DSC1001CC1-033.3333 compare to a standard quartz crystal oscillator?

This is a MEMS-based oscillator, not a quartz crystal. It offers better shock and vibration resistance, faster start-up, and a wider supply voltage range than typical quartz oscillators, while maintaining ±50 ppm frequency stability. The MEMS resonator also eliminates quartz supply-chain constraints.

Is DSC1001CC1-033.3333 AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up.
