Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Request the official datasheet from Mercury Electronics to validate electrical characteristics and reliability standards for the intended application environment.

Oscillators Selection Notes

Select this component when a precise 14.289843 MHz clock source is required for LVCMOS-compatible circuits. The choice is driven by the need for low-voltage operation at 1.8V and the integration of an enable/disable feature for energy efficiency. The small 2.0x1.6mm package size makes it suitable for space-constrained designs. Consider the operating temperature range and stability requirements relative to the specific application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'OE' suffix typically indicates the inclusion of an enable/disable control pin. These components are designed for general-purpose timing applications where low power consumption and small form factors are prioritized over high-frequency performance.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinout and envelope but different frequencies, such as 18QHTF21-13.1313-OE or 18QHTF21-8.300-OE, provided the frequency difference is acceptable. Cross-brand replacements require matching LVCMOS logic, 1.8V supply, 4-SMD package, and enable functionality.
