Product details

MEMS oscillator that sidesteps quartz startup and shock limits

Unlike a quartz crystal oscillator, the MEMS resonator is immune to the startup delays and shock/vibration sensitivity that plague quartz in automotive and industrial environments.

The DSC1001BI5-007.3728T carries AEC-Q100 qualification, so it is released for automotive stress and reliability testing — under-hood, cabin, or chassis domain. This is not a commercial-grade part with an extended temp range sticker; it is a qualified automotive component.

Package and footprint: 5.0mm x 3.2mm 4-SMD no-lead

Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm max. The MEMS construction means no quartz crystal to crack during reflow or vibration testing.

Frequently asked questions

Can DSC1001BI5-007.3728T replace a standard quartz crystal oscillator on my board?

Yes, if your design expects a 7.3728 MHz CMOS clock from a standard XO. The DSC1001 is a MEMS-based drop-in replacement for a quartz oscillator in the same 5.0 mm x 3.2 mm 4-pin SMD package. The MEMS resonator is more shock-tolerant and starts up faster than quartz — no external load capacitors needed.

Is DSC1001BI5-007.3728T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, meaning it is qualified for automotive-grade stress and reliability testing. Suitable for under-hood and cabin applications where the ambient temperature stays within -40°C to 85°C.
