Product details

Why a MEMS oscillator instead of a quartz can

The DSC1033BC1-050.0000T: At 50 MHz with a CMOS output and 3.3 V supply, this oscillator is a direct electrical replacement for a standard quartz-can oscillator in the same 5.0 mm × 3.2 mm SMD footprint — no board layout change needed.

Power budget and standby control

Typical supply current is 4 mA while oscillating — roughly one-tenth the draw of a comparable quartz oscillator at the same frequency — which matters for battery-powered or thermally constrained enclosures.

Frequently asked questions

Can DSC1033BC1-050.0000T replace a 50 MHz quartz oscillator on my existing board?

Yes — the DSC1033BC1-050.0000T is a drop-in replacement for a standard 50 MHz quartz-can oscillator in a 5.0 mm × 3.2 mm SMD footprint with CMOS output and 3.3 V supply. No layout change is required.

Is DSC1033BC1-050.0000T compatible with 3.3 V logic?

Yes — the supply voltage is 3.3 V and the output is CMOS, so it drives 3.3 V logic inputs directly.
