The DSC1001CI3-012.0000T is a MEMS-based oscillator from Microchip's DSC1001 series, delivering a 12 MHz CMOS output with ±20 ppm frequency stability.
Maximum supply current is 8 mA during active oscillation, keeping the thermal load low in dense PCB layouts.
±20 ppm over the full operating temperature range and supply voltage variation. This stability is sufficient for most automotive CAN, LIN, and Ethernet PHY reference clocks, though precision GPS or radar applications may require tighter (±10 ppm) parts.
Yes, it carries AEC-Q100 rating, meaning it has passed the automotive-grade stress tests (temperature cycling, ESD, latch-up) required for under-hood and cabin electronic modules.
Functionally yes — it outputs a CMOS clock at 12 MHz with ±20 ppm stability, directly replacing a quartz XO in the same frequency and output type. The MEMS resonator is more shock- and vibration-tolerant than quartz, which matters in automotive and industrial environments. Pin-compatibility depends on the existing footprint; the 4-VDFN package is a common 3.2 mm x 2.5 mm land pattern.
