MEMS oscillator with automotive-grade reliability
The DSC1001DL2-090.0000 is a 90 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±25 ppm frequency stability across a wide 1.8V to 3.3V supply range. The MEMS resonator eliminates quartz crystal aging and vibration sensitivity issues — a practical advantage for designs that see shock, vibration, or wide thermal cycling.
Power budget and supply flexibility
Maximum supply current is 8.7 mA at 90 MHz, and the disable mode drops to 15 µA — low enough to leave the oscillator powered continuously in a battery-operated system without draining the rail. The 1.8V to 3.3V input range means the same part can be fed from a 1.8V core rail or a 3.3V I/O rail, simplifying BOM consolidation across multi-voltage designs.
Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the footprint is compatible with standard reflow soldering and fits tight PCB layouts.
