Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for thermal and electrical specifications to guarantee reliable operation under intended environmental conditions.

Selection Notes

Select this component when a precise 92.0 MHz clock source is required for LVCMOS-compatible circuits. The 1.8V operating voltage makes it suitable for modern low-power digital systems. Consider the small 2.0x1.6 mm form factor for space-constrained designs. The inclusion of a power-down feature adds value for applications requiring active and inactive states to conserve battery life.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 1.8V LVCMOS format. The series is characterized by its small SMD package and integrated power management features. It serves as a direct replacement for other oscillators requiring similar electrical characteristics and physical dimensions in embedded electronics.

Replacement Considerations

Direct substitutes must match the 92.0 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical parameters such as current consumption and duty cycle before substitution.
