Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm electrical characteristics and packaging details. Ensure that the selected variant matches the required supply voltage and output load specifications for the target application. Cross-reference part numbers to distinguish between different pin configurations or tolerance levels offered within the MODbox series.
Selection Notes
Select this component when a precise 65.48175 MHz frequency is required for LVCMOS-compatible circuits. Consider the 3.3V operating voltage and the availability of a standby control feature for power management strategies. Evaluate the small form factor against available board space constraints and thermal requirements of the host system.
Part Context
This oscillator belongs to the MODbox series from Mercury Electronics, which specializes in frequency control products. The series offers various frequencies and packages tailored for modern electronic designs. Mercury Electronics has been a pioneer in the crystal industry since 1973, providing reliable timing solutions.
Replacement Considerations
Direct substitutes may include other 65.48175 MHz LVCMOS oscillators in similar SMD packages from compatible manufacturers. Verify pinout compatibility and electrical parameters before substitution. Alternative part numbers within the same family might offer different voltage options or tolerance levels.
