Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the 4-SMD no-lead package footprint aligns with your PCB layout constraints to ensure proper soldering and mechanical reliability during assembly.

Oscillators Selection Notes

Select this component when a precise 26 MHz timing reference is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. Consider the power-down feature if system energy efficiency is critical. Verify that the LVCMOS output swing is compatible with the input thresholds of the connected microcontroller or FPGA.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies with standardized 2.0x1.6mm footprints. The 'PD' suffix indicates the inclusion of a power-down pin for active standby control. These oscillators are designed for applications demanding stable clock signals in minimal board areas.

Oscillators Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Check datasheets for equivalent parts from other manufacturers offering identical pinout and electrical characteristics. Ensure thermal performance and frequency stability specs meet or exceed the original requirements.
