The DSC1001DE1-019.6608T is a 19.6608 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering a CMOS output with ±50ppm frequency stability across its -20°C to 70°C operating range. Its 1.8V to 3.3V supply voltage range lets it run off a 1.8V core rail or a 3.3V I/O rail without a separate regulator — one less part to source and place.
AEC-Q100 qualification for automotive and industrial
Lifecycle status is Active — no NRND or EOL flags, so you can design it into a new platform without worrying about a last-time-buy window.
4-SMD no-lead package and board-fit
Housed in a 2.50mm x 2.00mm 4-SMD no-lead package, it occupies about the footprint of a 0805 resistor — tight enough for a space-constrained ECU or sensor module. Seated height is 0.90mm max, so it fits under a conformal coating or inside a 2mm board-to-cover gap. Surface-mount with no leads means the solder joint is under the body — inspect with X-ray or a borescope if the board goes through reflow and you need to verify wetting.
