Product details

MEMS oscillator replacing quartz in automotive and industrial clocks

The DSC1001CE1-033.0000 is a MEMS-based XO (Standard) that generates a 33 MHz CMOS output with ±50 ppm frequency stability, operating from a 1.8V to 3.3V supply rail. The MEMS resonator eliminates the startup and aging drift typical of quartz crystals, giving a deterministic frequency over the part's life.

Power budget and standby behaviour

The Standby function is a logic-controlled pin that disables the output and reduces current — useful for automotive modules that wake on CAN or LIN activity.

Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, it fits tight PCB stacks in camera modules or compact control units.

Frequently asked questions

Is DSC1001CE1-033.0000 compatible with a 3.3V supply?

Yes. The supply voltage range is 1.8V to 3.3V, so it operates directly on a 3.3V rail without an external regulator.

What is the difference between DSC1001CE1-033.0000 and DSC1001CE2-033.0000?

The two order codes share the same MEMS XO family, 33 MHz frequency, and CMOS output. The suffix difference (CE1 vs CE2) typically indicates a different frequency stability grade or temperature range — confirm the exact spec variant in the datasheet before substituting on the same BOM line.

Can DSC1001CE1-033.0000 replace a standard quartz oscillator?

Yes. The MEMS-based XO is a drop-in replacement for a 33 MHz quartz oscillator with CMOS output and 1.8V–3.3V supply. The ±50 ppm stability matches many quartz specifications, and the MEMS construction adds shock and vibration immunity that quartz lacks.
