2 kHz MEMS XO — what the low frequency buys you
The DSC6083HI2A-002K000T: The 2 kHz frequency fits watchdog timers, low-speed clock supervisors, or power-management state machines where a crystal's fundamental resonance at that frequency would require an impractical die size.
AEC-Q100 — capable is not qualified; this one is
The part carries a named AEC-Q100 rating. That means it passed the stress tests (pre- and post-cond, high-temp operating life, ESD, latch-up) and comes with a PPAP-ready qualification package — the OEM auditor will ask for it, and this part has it.
Obsolete — sourcing and the last-time-buy reality
Microchip has marked this order code Obsolete. That means any remaining inventory is what the independent channel holds: surplus, overstock, or end-of-life buybacks. For a BOM that already uses this exact 2 kHz MEMS XO, the procurement path is a last-time-buy against remaining stock or a broker-sourced lot. For a new design, this part should not be specified — the AEC-Q100 qualification is valuable, but the obsolescence risk outweighs it unless the program has already locked in the footprint and cannot change.
Package and supply — fitting into a space-constrained board
That footprint matches the standard DSC60XX land pattern — no special pad geometry. The CMOS output swings rail-to-rail and drives a standard CMOS input directly. Tape & Reel packaging is the volume-shipment format; Cut Tape is also listed for prototyping or low-volume builds.
