Crystals Procurement Notes

Verify compliance with RoHS directives prior to procurement, as availability may vary by manufacturing batch. Confirm that the specific ordering suffix matches the required frequency tolerance and load capacitance parameters. Ensure the selected variant aligns with the intended application's thermal requirements and space constraints. Cross-reference datasheet revisions to confirm current production status and lead time estimates from authorized distributors.

Crystals Selection Notes

Select this component when a 24.576 MHz reference signal is required for wireless protocols such as WiMAX or WLAN. The 40 Ohm ESR value must be compatible with the oscillator circuit design to ensure stable startup. The ±30ppm initial tolerance and ±50ppm total stability define the timing accuracy budget. Consider the low-profile physical dimensions if vertical space on the PCB is limited compared to through-hole alternatives.

Crystals Part Context

This part belongs to the Meritek MXJ series of quartz crystals, which are engineered for surface mount technology.
