Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the supply voltage rails align with the 1.71 V to 1.89 V operational window. Ensure the PCB footprint matches the 2.0 x 1.6 mm package dimensions. Check for any recent part number revisions or obsolescence notices from the manufacturer.

Selection Notes

Select this component when a low-profile 26 MHz clock source is required for digital logic circuits. The CMOS output format simplifies interfacing compared to LVDS or HCSL options. Consider the 50 ppm stability sufficient for general synchronous data transfers. Evaluate power consumption constraints as the device operates at 1.8 V.

Part Context

This oscillator belongs to the IQXO-542 series, which focuses on small form-factor timing solutions. The series provides various frequencies optimized for microprocessors and memory interfaces. IQD Frequency Products integrates these components into broader timing portfolios serving automotive and industrial sectors.

Replacement Considerations

Cross-reference with other 26 MHz CMOS oscillators in the 2.0 x 1.6 mm package. Verify pinout compatibility if substituting with similar packages from other manufacturers. Ensure equivalent frequency stability and temperature range specifications.
