Why a MEMS oscillator instead of quartz?
The base resonator is MEMS, which means the part survives the reflow oven and board flex that can crack a quartz blank.
12.288 MHz — the audio and network sync frequency
12.288 MHz is the standard master clock for audio sample rates (48 kHz, 96 kHz, 192 kHz) and for certain telecom TDM buses. If your design uses an audio codec or a digital audio interface, this frequency matches the sample-rate generator without an extra PLL.
AEC-Q100 — automotive-grade timing, no extra qualification
For an under-hood ECU or a cabin-domain controller, this qualification saves the cost of a separate automotive-grade oscillator and the paperwork of a PPAP submission.
No last-time-buy window to track, no end-of-life notice to plan around.
Housed in a 4-SMD no-lead package measuring 0.098" x 0.079" (2.50 mm x 2.00 mm) with a seated height of 0.035" (0.90 mm). The small footprint fits space-constrained designs like ADAS cameras, telematics modules, and portable instruments.
