Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper assembly and electrical connectivity.

Selection Notes

Select this component when a stable 62.497656 MHz clock signal is required in space-constrained applications. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency is critical. Verify thermal performance within the specified operating temperature range for reliable long-term operation.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with consistent 2.0x1.6 mm packaging. It serves as a timing reference for digital circuits where size and power are limiting factors compared to larger through-hole or standard SMD packages.

Replacement Considerations

Direct substitutes must match the 62.497656 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering identical pinout and electrical characteristics to ensure functional equivalence without redesigning the host circuit.
