100 MHz clock source for automotive and industrial timing
The DSC1001BE2-100.0000T is a 100 MHz MEMS-based XO oscillator delivering a CMOS output with ±25 ppm frequency stability across its -20°C to 70°C operating range. Rated AEC-Q100, this oscillator is qualified for automotive applications where reliability under temperature and vibration is mandatory. The MEMS resonator provides inherent shock and vibration tolerance compared to quartz, reducing phase-noise degradation in harsh environments.
Supply voltage and power-down flexibility
A standby (power-down) function drops the supply current to 15 µA max, enabling battery-powered or sleep-mode systems to conserve energy when the clock is not needed. Active supply current is 8.7 mA max at 100 MHz, keeping the thermal footprint low in dense PCB layouts.
Package footprint and rework considerations
Housed in a 4-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the part fits tight spaces and is compatible with standard reflow soldering profiles. The no-lead construction means the pads are flush with the package bottom — rework requires a hot-air station with a fine nozzle; the small thermal mass reflows cleanly if the board is preheated to 100°C.
