The DSC1001CE1-125.0000T: This is a 125 MHz MEMS-based oscillator with CMOS output, qualified to AEC-Q100 and rated for -20°C to 70°C ambient — the temperature band for cabin infotainment and body-control modules, not the engine bay.
Standby power-down for battery-sensitive modules
Supply-voltage flexibility and package footprint
The 1.8V–3.3V supply range lets it run from a 1.8V core rail or a 3.3V I/O rail without a separate level translator — the output swings CMOS to match the supply. The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm max — a standard footprint shared by many MEMS and quartz oscillators, so the board layout is straightforward.
