The DSC1001CE2-040.0000T is a 40 MHz MEMS-based oscillator (XO) that outputs a CMOS-level clock — a direct drop-in replacement for a quartz-based can oscillator in the same 3.2 mm x 2.5 mm 4-SMD footprint.
Operates from a single 1.8V to 3.3V supply — the wide input range lets it run off a 3.3V rail or a lower-voltage core supply without an extra regulator.
Yes — it is a direct functional replacement for a 40 MHz quartz-based XO with CMOS output, in the same 3.2 mm x 2.5 mm 4-SMD no-lead footprint. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, which is the main reason to switch.
Yes, it carries an AEC-Q100 rating, meaning it has passed automotive-grade stress tests (temperature cycling, ESD, latch-up) and is suitable for under-hood or cabin electronics that must survive the -20°C to 70°C operating range with margin.
