Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD package footprint matches your PCB layout constraints. Check for any specific environmental operating temperature ranges required by your application environment to ensure reliable performance under all conditions.

Oscillators Selection Notes

Select this component when a 28.3116 MHz clock source is required with low voltage operation. Consider the LVCMOS output level compatibility with downstream logic families. Evaluate the physical size constraints as the 2.0x1.6mm package is small. Assess the need for power management features such as the standby mode for battery-operated or energy-efficient designs. Compare against other frequencies if the exact 28.3116 MHz is not strictly necessary.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various standard frequencies within a compact SMD form factor. The 'PD' suffix indicates the inclusion of a power down or standby feature. Mercury Electronics specializes in quartz crystals and frequency control products, providing solutions for timing applications across multiple industries.

Oscillators Replacement Considerations

Direct replacements must match the 28.3116 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. Cross-reference with other manufacturers offering similar low-profile oscillators with standby functions.
