This means the part is qualified for under-hood or chassis-mounted ECUs where quartz oscillators may fail under sustained vibration or thermal cycling. The 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails, so the same BOM line can serve multiple voltage domains.
Frequency stability and supply current limits
Frequency stability is ±50 ppm, which includes temperature, supply variation, and aging. For a 20 MHz clock, ±50 ppm translates to ±1,000 Hz of absolute jitter budget — enough for most MCU and CAN bus timing requirements, but tight for high-speed serial interfaces like USB or Ethernet that demand ±25 ppm or better. The disable current is still significant — if the oscillator is gated for low-power sleep modes, the 22 mA draw may dominate the sleep budget. A separate load switch ahead of the supply pin may be needed for sub-mA standby targets.
Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. X-ray inspection after reflow is recommended to verify voiding under the package. Surface-mount mounting is assumed; no through-hole variant exists in this series. The low profile (0.90 mm) suits compact designs where board-to-board clearance is tight.
