DSC6001CI1A-016.9344 is officially marked Obsolete by Microchip Technology.
AEC-Q100 qualification and automotive fit
Rated AEC-Q100 — this means the oscillator has passed automotive-grade reliability stress, temperature cycling, and ESD qualification. The qualification documentation (PPAP) should be available from Microchip for the OEM auditor.
16.9344 MHz with ±50 ppm stability — timing budget
This stability level is adequate for most standard communication interfaces (USB, 100BASE-T Ethernet, audio codecs) where the total timing budget across the system clock tree is ±100 ppm or better. The CMOS output swings rail-to-rail between 1.71 V and 3.63 V, so it can interface directly with 1.8 V, 2.5 V, or 3.3 V logic without a level shifter.
MEMS resonator and low-power profile
Package and board layout notes
4-SMD, No Lead package measuring 3.20 mm x 2.50 mm x 0.90 mm. Surface-mount with a standard land pattern — no through-hole or via-in-pad required. The small footprint frees board space for adjacent decoupling capacitors. No external load capacitors are needed (unlike quartz crystals); the MEMS oscillator is self-contained.
