Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application 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 specifications. Check for any specific environmental operating temperature constraints defined in the official datasheet to guarantee reliable performance under intended conditions.

Oscillators Selection Notes

Select this component when a precise 26.25 MHz reference is required for LVCMOS-compatible digital logic. The integrated enable pin offers power management advantages over non-controlled oscillators. Consider the 1.8V supply requirement to ensure compatibility with modern low-power processors. The small form factor makes it suitable for space-constrained designs where standard through-hole or larger SMD packages cannot fit.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically covers various frequencies within the MHz range, all sharing similar electrical characteristics and package dimensions. The 'OE' suffix likely denotes specific ordering or packaging options provided by the manufacturer or distributor channels.

Oscillators Replacement Considerations

Direct replacements must match the 26.25 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD package outline. Verify pinout compatibility and electrical parameters such as phase noise and jitter if critical. Consult manufacturer cross-reference lists for verified equivalents.
