Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. 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 to avoid assembly issues. Cross-reference the manufacturer datasheet for thermal handling guidelines during soldering processes.

Oscillators Selection Notes

Select this component when a precise 24.999 MHz clock source is required for low-power applications. The LVCMOS output ensures compatibility with standard digital logic families. Consider the small 2.0x1.6 mm form factor for space-constrained designs. Verify that the operating temperature range meets your environmental conditions prior to integration into the final product assembly.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 1.8V LVCMOS format. The 'PD' suffix indicates the inclusion of a power-down control feature. These components are designed for high-reliability timing applications in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 24.999 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical to the application.
