MEMS oscillator with wide supply tolerance
The DSC1001BC1-025.0000 is a 25 MHz MEMS-based XO (Standard) with CMOS output, spanning a 1.8V to 3.3V supply range without needing a separate regulator or level translator. Frequency stability is ±50 ppm, tight enough for a 25 MHz reference driving a 100BASE-TX PHY or a Cortex-M4 PLL without external trimming.
AEC-Q100 qualification at commercial temperature
The AEC-Q100 stamp means the part passed automotive-level stress tests (preconditioning, temperature cycling, HAST, ESD) — relevant for infotainment, telematics, or cabin-domain controllers where the ambient stays above freezing.
4-VDFN package and board integration
Housed in a 4-VDFN measuring 5.00mm x 3.20mm with a seated height of 0.90mm — the 0.50 mm pitch pads are on the bottom, so the PCB land pattern must match the datasheet footprint for solder joint reliability.
Active lifecycle — no NRND flags
The base product number DSC1001 covers multiple frequencies and stability grades; the full order code DSC1001BC1-025.0000 selects the specific 25 MHz, ±50 ppm variant.
