Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required frequency tolerance and load conditions. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Cross-reference the manufacturer datasheet for absolute maximum ratings before integration.
Selection Notes
Select this component when a standard frequency reference near 86.6 MHz is required with low power consumption. The LVCMOS interface suits digital logic families operating at 1.8V. Consider the ±50 ppm stability requirement against system jitter budgets. The enable pin allows for dynamic power saving during idle states.
Part Context
This part belongs to the Mercury Electronics standard XO series, utilizing quartz crystal technology for frequency stability. The manufacturer has extensive experience in quartz components, ensuring reliable performance across various industrial and commercial temperature ranges typical for such oscillators.
Replacement Considerations
Direct substitutes must match the 86.603 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent stability specifications and pinout compatibility before replacement.
