Obsolete — sourcing for existing BOM lines
This means the original manufacturer no longer produces or sells the part through its authorized channel. The part was qualified to AEC-Q100, so it was originally intended for automotive applications. If you are sourcing a replacement for a production board, verify that the replacement part also carries AEC-Q100 certification to maintain the same reliability qualification.
MEMS resonator, CMOS output, wide supply range
This is a MEMS-based oscillator (XO) with a CMOS output stage. The supply voltage spans 1.71V to 3.63V, which covers common 1.8V, 2.5V, and 3.3V logic rails without an external regulator. The available frequency range is 1 MHz to 80 MHz, but this specific blank unit must be programmed by the user before use. The 4-SMD, no-lead package measures 2.00mm x 1.60mm with a seated height of 0.89mm.
