Why choose a MEMS oscillator over a quartz crystal
The 125 MHz fixed output is generated directly from the MEMS die without a PLL, so jitter is deterministic and the part powers up to frequency within microseconds.
Automotive-grade qualification and supply voltage flexibility
The supply voltage range of 2.25V to 3.6V covers both 2.5V and 3.3V logic rails without a separate regulator.
Package, footprint, and board-level considerations
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The 0.50mm pitch of the outer pads requires a 4-layer board for reliable fan-out; two-layer designs can break out only the inner rows.
