Product details

What this MEMS oscillator brings to an automotive clock tree

Supply voltage flexibility and package footprint

Supply voltage range 1.8V to 3.3V lets the same oscillator serve 1.8V-core SoCs and 3.3V I/O banks without an external level translator — a single BOM line covers multiple rail domains. The 4-SMD no-lead exposed pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — standard 7x5 footprint that matches many quartz oscillator land patterns, so a board designed for a quartz XO can often take this MEMS part without a layout change.

Frequently asked questions

How can I order DSC1001AI1-033.3330 or request a quote?

This part is Active and available through independent distribution. Submit an RFQ with your target quantity — we confirm availability and current pricing at quote time.

Is DSC1001AI1-033.3330 a direct replacement for a standard quartz oscillator?

Yes, in most cases. The DSC1001 is a MEMS oscillator with a standard 7x5 mm SMD footprint and CMOS output — it drops into the same land pattern as many quartz XOs. The MEMS resonator is more shock and vibration tolerant than quartz, which is why it carries AEC-Q100 automotive qualification.

What is the frequency stability of DSC1001AI1-033.3330?

Frequency stability is ±50 ppm over the operating temperature range and supply voltage variation — tight enough for most automotive and industrial clocking applications including 100BASE-T1 Ethernet.

Does DSC1001AI1-033.3330 support standby power down?

Yes, the standby (power down) function disables the output and drops current to 15 µA max — the oscillator stops, but the supply rail can remain connected.
