Product details

MEMS resonator reliability vs. quartz in automotive environments

Standby function and supply voltage flexibility

The supply voltage range spans 1.8V to 3.3V, so the same oscillator can feed a 1.8V FPGA bank, a 2.5V SerDes PLL, or a 3.3V microcontroller without a level translator — one BOM line covers three power domains.

Package footprint and layout consideration

Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The 4-pin footprint matches industry-standard MEMS and quartz oscillator pinouts — no layout change needed if swapping from a quartz XO.

Product status is Active — Microchip continues to manufacture and support the DSC1001 series.

Frequently asked questions

Is DSC1001CL1-066.0000T automotive qualified?

Yes, it carries AEC-Q100 rating, meaning it passed the automotive-grade reliability stress tests.

Does DSC1001CL1-066.0000T have a standby function?

Yes, a Standby (Power Down) pin disables the output and reduces supply current to 15 µA max. This allows the oscillator to be gated off in low-power system states without a separate load switch.

How does DSC1001CL1-066.0000T compare to a standard quartz oscillator?

The DSC1001 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer better shock and vibration immunity, faster start-up, and wider frequency stability over temperature — at the cost of slightly higher phase noise floor compared to high-end quartz OCXOs. For most automotive and industrial clocking needs, the MEMS advantage in ruggedness outweighs the noise difference.

Is DSC1001CL1-066.0000T compatible with 3.3V logic?

Yes, the supply voltage range includes 3.3V, and the CMOS output is compatible with 3.3V logic levels. The output swings rail-to-rail, so it drives 3.3V LVCMOS inputs directly.
