Product details

The supply voltage spans 1.8V to 3.3V, so the same part number works across 1.8V MCU I/O and 3.3V peripheral rails without a level translator on the clock line.

Stability and power budget for always-on modules

Frequency stability is ±10 ppm — tight enough for a CAN bus bit-time reference where the tolerance budget is typically ±0.5% of the bit period.

Package and footprint for reflow assembly

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 standard 7x5 mm ceramic oscillator footprint, pin-compatible with quartz XO replacements. Surface-mount with exposed pad for thermal relief; the MEMS die is less sensitive to reflow profile than quartz, but standard JEDEC MSL handling applies.

Frequently asked questions

Is DSC1001AL5-001.8432 pin-compatible with standard quartz oscillators?

Yes — the 4-SMD, No Lead Exposed Pad package with 7.00 mm x 5.00 mm footprint matches the industry-standard 7x5 mm ceramic oscillator land pattern. The MEMS die is a drop-in replacement for quartz XOs at the same frequency and output type.

Does DSC1001AL5-001.8432 work with a 3.3V supply?

Yes — the supply voltage range is 1.8V to 3.3V, so 3.3V is within the operating envelope. No external regulator needed if the rail is within that window.
