Product details

Operating from a 1.7V to 3.6V supply, the oscillator runs directly off a 1.8V or 3.3V rail without an external LDO — the wide range covers both core and I/O voltage domains in mixed-voltage designs. Active current draw is 7.4 mA max at 50 MHz — well within the budget of a typical automotive power tree.

Housed in a 4-SMD, no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the footprint matches industry-standard 7x5 mm XO land patterns — no layout change needed when replacing a quartz oscillator.

Frequently asked questions

Does the DSC1003AI1-050.0000 meet AEC-Q100 automotive qualification?

Yes, it carries AEC-Q100 rating, which qualifies it for automotive applications including under-hood and chassis domains where temperature and vibration stress are high.

Can this oscillator replace a standard quartz XO in an existing design?

The DSC1003AI1-050.0000 is a direct pin-compatible replacement for standard 7x5 mm quartz XOs with CMOS output — same footprint, same supply range, and no external load capacitors required. The MEMS construction adds shock immunity and faster startup.

Is the DSC1003AI1-050.0000 compatible with a 3.3V supply?

Yes, the supply range is 1.7V to 3.6V, so both 3.3V and 1.8V rails are supported without any external level shifting.
