Product details

Because it is a current-series MEMS oscillator, the supply chain is not constrained by quartz crystal lead times or allocation cycles that sometimes hit legacy crystal oscillators.

The supply voltage range of 1.8V to 3.3V lets this oscillator drop into designs with a 1.8V core rail or a 3.3V I/O bank without a separate level translator.

5.0 mm × 3.2 mm no-lead package — footprint and reflow

Housed in a 4-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm. Surface-mount assembly on standard FR-4 with a lead-free reflow profile is straightforward; no special bake-out or moisture sensitivity handling is required beyond the standard MSL level.

Frequently asked questions

What is the closest pin-compatible alternative to DSC1001BI5-066.6666T?

Within the DSC1001 series, any member with the same 4-SMD no-lead package and 1.8V–3.3V supply range is footprint-compatible. For the same 66.6666 MHz frequency, the DSC1001BI5-066.6666T is the specific variant; a different stability grade or temperature range would change the suffix. No direct second-source cross from another manufacturer is documented.
