The MEMS resonator offers faster startup and better shock resistance than a quartz crystal — useful in applications where the oscillator powers up and down frequently, such as keyless entry modules or telematics control units.
Supply range and standby power-down
Operating from 1.7V to 3.6V, this oscillator can be powered from a 1.8V or 3.3V rail without a separate regulator — the wide range covers both logic families and allows a single BOM line for mixed-voltage designs. Active current is 8 mA max — typical for a 49.5 MHz CMOS oscillator; the MEMS core consumes less than a quartz equivalent at the same frequency, which helps keep the thermal budget tight in a sealed enclosure.
4-VDFN package and board layout
Housed in a 4-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator fits compact PCB layouts where board space is at a premium — typical for ADAS cameras, radar modules, or infotainment head units.
