The DSC6001JE1B-020.0000T is an AEC-Q100 rated MEMS-based XO that delivers a 20 MHz CMOS clock with ±50 ppm frequency stability across its -20°C to +70°C operating range. Qualification to AEC-Q100 means this part has passed the automotive-grade stress tests (temperature cycling, ESD, latch-up) required for under-hood and cabin electronics — but the -20°C to +70°C temperature grade limits it to passenger-compartment or controlled ambient, not the full -40°C to +125°C engine bay.
The 1.8V to 3.3V supply range lets the oscillator run directly from a 1.8V core rail or a 3.3V I/O rail without an external level translator — the same BOM position serves both voltage domains. The enable/disable function (pin-controlled) pulls the CMOS output to high-impedance when de-asserted, cutting typical supply current from 1.3 mA to near-zero — useful for gating the clock in a low-power sleep state without removing power from the oscillator.
4-VLGA footprint and board layout
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm, the DSC6001JE1B-020.0000T occupies roughly the same PCB area as a standard 2.5 mm x 2.0 mm crystal — the four-land pattern is straightforward to route on a two-layer board.
Active production with AEC-Q100 traceability
The AEC-Q100 rating provides the PPAP-level traceability that automotive OEMs and Tier-1 suppliers require for production releases.
