Product details

Supply range and power budget across the rail

The 1.8V to 3.3V supply range means the same oscillator BOM line serves a 1.8V core rail and a 3.3V I/O rail without a level translator — the CMOS output swings with the supply, so the receiving logic sees a valid high level at either voltage.

Frequency stability and timing margin

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — the exposed pad underneath provides a thermal path to the PCB ground plane, which matters if the oscillator sits near a hot regulator or processor in a sealed enclosure.

The DSC1001 series is an established MEMS oscillator family; the AL5 suffix denotes the ±10ppm stability grade and 1.8V–3.3V supply option.

Frequently asked questions

Is DSC1001AL5-012.0000T a drop-in replacement for a quartz crystal oscillator?

Yes, in most designs. The DSC1001AL5-012.0000T is a MEMS-based XO with CMOS output in a standard 4-SMD footprint — it is pin-compatible with many quartz XOs of the same package and output type. The key difference is the MEMS resonator is more resistant to shock and vibration, and the part carries AEC-Q100 qualification, which quartz XOs often do not. Confirm the supply voltage range (1.8V–3.3V) and output load (CMOS) match your circuit.

Does DSC1001AL5-012.0000T support 1.8V operation as well as 3.3V?

Yes. The supply voltage range is 1.8V to 3.3V, and the CMOS output swings rail-to-rail with the supply. At 1.8V the output high level is approximately 1.8V, so the receiving logic must accept that as a valid high. The frequency stability of ±10ppm is maintained across the full supply range.

What is the AEC-Q100 qualification level of DSC1001AL5-012.0000T?

The DSC1001AL5-012.0000T is rated AEC-Q100, which means it has passed the automotive-grade stress tests including temperature cycling, ESD, and latch-up.
