Product details

It operates from a 1.8 V to 3.3 V supply rail, drawing a maximum of 7.2 mA, and includes a Standby (Power Down) function that reduces supply current to 15 µA max when disabled. AEC-Q100 qualification confirms reliability for automotive-grade applications – the MEMS resonator and CMOS output stage are screened for thermal cycling, vibration, and extended temperature stress typical of cabin and chassis domains.

Active lifecycle – available for new designs

No pin-compatible successor or second source is listed; the DSC1001BI5-050.0000T is the current production variant for this frequency and stability grade.

4-SMD no-lead footprint – board-level fit

Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this oscillator is a direct surface-mount replacement for standard quartz oscillators in the same footprint. The 1.8 V to 3.3 V supply range means a single BOM line covers both 3.3 V and 1.8 V clock domains without a level translator.

Frequently asked questions

Does the DSC1001BI5-050.0000T have a standby or power-down mode?

Yes, the oscillator includes a Standby (Power Down) function. When disabled, the supply current drops to 15 µA max – useful for battery-backed systems that need to cut clock noise during sleep.

Can the DSC1001BI5-050.0000T replace a quartz crystal oscillator?

Yes – it is a drop-in XO replacement. The MEMS resonator provides the same timing function as a quartz crystal but with better shock and vibration immunity (common in MEMS oscillators) and a tighter ±10 ppm stability over temperature. Pinout and footprint match standard 4-SMD crystal oscillators.
