Obsolete MEMS oscillator — sourcing through independent channels
The DSC6001MI2A-027.1200T is officially obsolete.
Automotive-grade 27.12 MHz reference with ±25 ppm stability
This MEMS-based XO (Standard) delivers a 27.12 MHz CMOS output with ±25 ppm frequency stability across the full -40°C to +85°C industrial temperature range. The 1.71V–3.63V supply rail covers 1.8V, 2.5V, and 3.3V logic families without an extra regulator — one BOM line serves multiple voltage domains. It is suited for under-hood ECUs, ADAS sensor modules, and chassis-domain controllers where a standard commercial oscillator would not hold the grade.
MEMS resonator vs quartz — smaller footprint, same timing budget
The 4-VFLGA package measures 2.00 mm × 1.60 mm with a seated height of 0.89 mm — roughly half the footprint of a comparable quartz SMD oscillator.
