Product details

AEC-Q100 qualified 54 MHz MEMS oscillator

The DSC1001CE2-054.0000T is an AEC-Q100 qualified MEMS-based XO (Standard) oscillator delivering a 54 MHz CMOS output with ±25ppm frequency stability across -20°C to 70°C.

Wide supply range and low power standby

Supply voltage spans 1.8V to 3.3V, so the same oscillator works on a 1.8V core rail, a 2.5V I/O rail, or a 3.3V peripheral rail—no separate regulator needed when crossing voltage domains.

Package and deployment context

Housed in a 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm—a compact footprint that fits tight PCB layouts in automotive body controllers or camera modules. Operating temperature range -20°C to 70°C covers cabin and chassis environments but does not extend to full under-hood (125°C) conditions—confirm the ambient temperature at the oscillator's board location before committing. Surface-mount assembly with no-lead terminations requires a standard reflow profile; no special handling beyond typical MSL precautions for a MEMS device.

Frequently asked questions

Is DSC1001CE2-054.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, which means it has passed automotive-grade qualification including temperature cycling, ESD, and latch-up tests. The PPAP documentation is available for OEM audit.

Can DSC1001CE2-054.0000T be used as a drop-in replacement for an older 54 MHz quartz oscillator?

If the older oscillator is a 3.3V or 1.8V CMOS-output, 4-pin SMD device with the same 3.20mm x 2.50mm footprint, it is a functional drop-in. The MEMS resonator offers better shock and vibration immunity than quartz. Verify the standby pin function matches the old part's enable logic.

Is DSC1001CE2-054.0000T compatible with 3.3V logic?

Yes, the supply voltage range includes 3.3V, and the CMOS output swings rail-to-rail, so it directly drives 3.3V logic inputs. For 1.8V or 2.5V logic, the same part works by setting the supply to the target voltage.
