The DSC1001DE3-080.0000T is a MEMS-based oscillator from Microchip's DSC1001 series, delivering a fixed 80 MHz CMOS clock with ±20 ppm stability across its operating range. It runs on a 1.8V to 3.3V supply, drawing 16.6 mA max, and includes a standby (power-down) function that drops supply current to 15 µA — useful for battery-powered or intermittent-duty systems where the clock tree must be gated off when idle.
Automotive-grade qualification with commercial temperature limits
That limits it to cabin or climate-controlled modules, not under-hood or engine-bay positions where ambient temperature exceeds 70°C.
4-VDFN package — footprint and reflow considerations
The 4-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight board layouts but demands a precise solder-paste stencil and reflow profile to avoid tombstoning or poor wetting on the small pads.
