A MEMS-based XO (Standard) delivering a 48 MHz CMOS output from a 4-VDFN package, the DSC1001CI3-048.0000 is qualified to AEC-Q100 — the automotive IC reliability standard covering temperature cycling, ESD, and latch-up immunity across the full -40 to 85°C operating range. The 48 MHz frequency is a common reference for CAN-FD controllers, automotive Ethernet PHYs, and high-end MCU clock trees; the ±20 ppm frequency stability holds the timing budget for these serial buses without external compensation.
Supply, standby, and package
Operates from a 1.7V to 3.6V supply, drawing 10.5 mA max in active mode. Housed in a 3.20 mm x 2.50 mm 4-VDFN with a seated height of 0.90 mm.
Active production, automotive-grade sourcing
The AEC-Q100 rating means this part is production-qualified for automotive OEMs and tier-1 suppliers — the PCN/EOL watch is standard for the DSC1001 series, but no discontinuation has been announced.
