The 4-VDFN package (5.00mm x 3.20mm, 0.90mm seated height) fits compact PCB layouts common in ADAS modules, infotainment, and telematics control units.
Operating from 1.7V to 3.6V, the oscillator covers 1.8V, 2.5V, and 3.3V logic rails without an external regulator — a single supply rail serves the entire clock tree.
Yes, it is a direct drop-in replacement for a quartz-based XO at 50 MHz with CMOS output. The MEMS resonator is more resistant to vibration and shock than quartz, and the ±25 ppm stability matches many quartz oscillator grades. Verify the supply voltage range (1.7V–3.6V) and package footprint (4-VDFN, 5.00mm x 3.20mm) match your PCB layout.
The difference lies in the frequency stability specification. The 'BI2' variant is rated at ±25 ppm, while the 'BI1' variant is typically ±50 ppm. For applications requiring tighter timing margin — such as CAN FD or Ethernet PHY reference clocks — the ±25 ppm grade provides better accuracy over temperature and aging.
Yes. The supply voltage range is 1.7V to 3.6V, which includes 2.5V. The oscillator will operate within specification at 2.5V without any external level shifting.
