Obsolete MEMS oscillator — sourcing reality
Key ratings for fit into a 7.3728 MHz timing circuit
The 7.3728 MHz frequency is a standard multiple for UART baud-rate generation — it divides cleanly to common rates like 115200 baud without fractional-N PLL overhead.
Supply voltage flexibility and automotive-grade qualification
The supply range spans 1.71 V to 3.63 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without an external LDO — one oscillator serves multiple power domains on the same board. That qualification also makes it suitable for industrial and outdoor applications where the temperature and vibration envelope exceeds commercial-grade limits.
