Frequency stability and timing accuracy
The ASE-25.000MHZ-L-C-T: That translates to a worst-case timing error of ±50 µs per second, or roughly ±4.3 seconds per day — adequate for UART, SPI, and I²C clocking, USB full-speed framing, and most microcontroller PLLs that derive their core clock from it. A design requiring sub-1.5 ppm for precision timestamping or Ethernet PHY reference would need a TCXO or OCXO instead; this part carries no such qualification.
Package footprint and board integration
No exposed paddle is specified; thegnd pad under the body handles mechanical anchoring and thermal relief. Confirm decoupling topology against the datasheet — the 3.3 V rail feeding the oscillator should bequiet before the device is enabled, since the CMOS output integrity degrades if supply noise modulates the reference crystal.
