IXA10-FBFF10-26.000MHZ

Crystals Overview

The ILSI IXA10-FBFF10-26.000MHZ is a parallel fundamental quartz crystal operating at a nominal frequency of 26 MHz. It features a load capacitance of 10 pF and a maximum series resistance of 80 Ohms within the 24–25.999999 MHz range, though specific data for 26 MHz lists 80 Ohms max ESR. Frequency tolerance options include ±30 ppm or ±50 ppm at 25°C, with stability over temperature ranging from ±15 ppm to ±50 ppm depending on configuration. The component utilizes an AT-cut design in a 4-SMD no-lead package measuring 1.60 mm x 1.20 mm.

Crystals Procurement Notes

Verify the specific frequency tolerance requirement (±30 ppm vs ±50 ppm) against the target application's clock accuracy specifications before procurement. Confirm that the 80 Ohms maximum equivalent series resistance aligns with the oscillator circuit drive conditions. Ensure the 1.60mm x 1.20mm footprint matches the PCB land pattern design. Cross-reference the RoHS compliance status if environmental regulations are strict for the final assembly.

Crystals Selection Notes

Select this component when a compact 26 MHz reference is required for space-constrained digital interfaces. The choice between ±30 ppm and ±50 ppm tolerance should depend on the system's jitter budget and phase noise requirements. Consider the 10 pF load capacitance compatibility with the host microcontroller or FPGA pins. Evaluate the thermal stability needs against the available temperature range options in the IXA10 series lineup.

Crystals Part Context

This part belongs to the ILSI IXA10 series of ultra-miniature ceramic package quartz crystals. The series offers various frequencies from 16 MHz to 72 MHz in a consistent 4-SMD no-lead form factor. It serves as a passive timing element for synchronous digital circuits requiring precise clock generation without active oscillation components.

Crystals Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 10 pF load capacitance, and 1.60mm x 1.20mm footprint. Verify equivalent series resistance limits and aging rates to ensure signal integrity is maintained across the supply chain.
