The DSC1001DL1-008.0000T: This is an 8 MHz MEMS-based XO (standard oscillator) from Microchip's DSC1001 series, delivering a CMOS output across a 1.8V to 3.3V supply range. That temperature range puts it in the under-hood or engine-bay domain, not just cabin electronics.
Frequency stability and power budget
The 6.3 mA max supply current at 8 MHz is modest; for a battery-backed module that sleeps most of the time, the standby pin drops current to 15 µA typical, keeping the quiescent draw negligible. The wide supply range (1.8V to 3.3V) lets it run off a 3.3V rail or a 1.8V core supply without a level translator on the output — the CMOS output swings rail-to-rail, so the downstream logic sees a clean signal at either voltage.
Housed in a 4-SMD, No Lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm. Surface-mount reflow with standard lead-free profile; the part is ROHS-compliant by design.
Product status is Active — Microchip still lists it as a current production part.
