What the AEC-Q100 rating means for your BOM
The DSC6101CE2A-000.0000 carries an AEC-Q100 qualification — this is the automotive IC stress test standard covering temperature range, reliability, and PPAP documentation.
MEMS resonator and blank-programmable frequency
A MEMS base resonator replaces the traditional quartz crystal — the part is blank-programmable (user must program the output frequency) over a 1 MHz to 100 MHz range. This means a single order code can serve multiple frequency points on the BOM if you have the programming infrastructure; otherwise each frequency variant requires a separate programmed part. The CMOS output and Enable/Disable pin let the oscillator be gated off in firmware, pulling the 3 mA typ supply current to near zero for sleep states — useful in battery-backed modules where the clock tree shuts down between transactions.
Supply voltage and frequency stability
The ±25ppm total frequency stability includes initial tolerance, temperature drift, and supply variation, so the clock tree accuracy is bounded across the full operating envelope.
Obsolete lifecycle — sourcing reality
The DSC6101CE2A-000.0000 is marked as Obsolete by Microchip Technology. No pin-compatible drop-in replacement has been identified; a board spin or frequency-reprogramming of a different oscillator may be required for new builds.
