For a production line that already qualifies this MEMS oscillator, the immediate decision is whether to secure a last-time-buy quantity or migrate to a current-series alternative.
Supply voltage spans 1.71V to 3.63V, so it works from a 1.8V or 3.3V rail without an external regulator. Rated -40 to +85°C with ±25 ppm frequency stability. That stability band holds across the full temperature range — a ±25 ppm window at 64 MHz translates to ±1.6 kHz of absolute frequency error, tight enough for a 100BASE-TX Ethernet reference or a CAN bus clock without additional ppm budget from the PHY. If your BOM specifies AEC-Q100, the DSC6001CI2A-064.0000T carried that grade; a commercial-grade replacement would require a re-qualification step.
Sourcing an obsolete oscillator — what to expect
No minimum order quantity is assumed; we quote against your BOM line quantity. The closest functional replacement would be a current-series DSC60XX part with the same 64 MHz frequency, CMOS output, and AEC-Q100 rating — but the exact order code suffix (temperature range, stability grade) must be verified against the original BOM specification before substitution.
