MEMS oscillator with automotive-grade reliability
The DSC1001BI1-048.0000T is a 48 MHz MEMS-based XO (Standard) with CMOS output, built for applications that need a quartz alternative with better shock and vibration immunity. That makes it a natural fit for engine-control modules, transmission controllers, or any 12V/24V vehicle electronics where the ambient temperature inside the enclosure can hit 85°C.
The 1.8V to 3.3V supply range covers the common digital core and I/O rails — no extra regulator needed when moving between a 3.3V MCU and a 1.8V FPGA bank. Maximum supply current is 7.2 mA, which is typical for a 48 MHz CMOS oscillator; the standby (power-down) function drops that to 15 µA when the clock is gated off, useful for battery-backed RTC or sleep-mode power budgets.
The 4-SMD, No Lead package measures 5.00 mm × 3.20 mm with a seated height of 0.90 mm. The 0.197" × 0.126" footprint is a standard 5×3.2 mm oscillator land pattern — no via-in-pad or buried traces required.
