Why a MEMS oscillator beats quartz for this 9.9 MHz timing slot
At 9.9 MHz with ±50 ppm frequency stability, the clock edge stays within the timing budget across the full -40 to +125°C range — no warm-up drift, no activity dip from quartz aging.
Automotive-grade qualification and operating envelope
Supply voltage flexibility and package footprint
The 1.8V to 3.3V supply range lets the same oscillator serve a 1.8V-core MCU and a 3.3V peripheral bus without a separate level translator — the CMOS output swings rail-to-rail. Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm — the small footprint saves board area, but the 4-pin land pattern demands a controlled solder-paste volume to avoid skew during reflow.
