• Embedded electronics circuits

Procurement Notes

Verify the specific frequency tolerance and stability requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no lead package footprint matches the PCB layout specifications to guarantee proper mounting and electrical connectivity.

Selection Notes

Select this component when a low-profile surface mount oscillator is required for 13.05 MHz applications. Consider the LVCMOS output compatibility with downstream digital logic. Evaluate the thermal operating range and power consumption characteristics relative to the system's environmental constraints and energy efficiency goals.

Part Context

This part belongs to the 18QHTF21 series of clock oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small form factor. These components are designed for high-reliability timing applications in consumer and industrial electronics where space savings and stable clock signals are critical.

Replacement Considerations

Direct substitutes must match the 13.05 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no lead package dimensions. Verify pinout compatibility and electrical parameters such as jitter and phase noise if available in competitor datasheets.
