Crystals Procurement Notes

Verify the specific operating frequency and package variant against the official manufacturer datasheet prior to ordering, as distributor listings may contain conflicting specifications regarding the nominal frequency. Confirm that the 4-SMD, No Lead form factor aligns with your PCB footprint requirements. Ensure the ±20ppm tolerance meets your system's timing accuracy constraints. Cross-reference the load capacitance of 8pF with your oscillator circuit design to guarantee proper resonance. Request the latest technical documentation directly from Geyer Electronic America, Inc. to validate current manufacturing status and pinout definitions before finalizing procurement.

Crystals Selection Notes

Select this component when a 52 MHz quartz crystal with 8pF load capacitance is required for surface-mount designs. Consider the 100 Ohm ESR specification for oscillator circuit compatibility. Evaluate the ±20ppm stability against your application's jitter and phase noise requirements. Ensure the 4-SMD package dimensions fit within your board space constraints. Verify that the device supports the voltage and temperature ranges defined in your system specifications.
