Crystals Procurement Notes

Verify the manufacturer designation carefully, as some listings incorrectly attribute this part to TXC Corporation or Texas Instruments. Confirm the specific FTS branding on the component marking or official datasheet before procurement. Ensure the ordering suffix matches the required tape and reel configuration if applicable. Cross-reference the ESR and load capacitance values with your circuit design requirements to ensure compatibility.

Crystals Selection Notes

Select this component when a 14.7456 MHz reference is required for video or data transmission applications due to its standard frequency division properties. Consider the ±30 ppm stability requirement against your system's jitter budget. Evaluate the 40 Ohm ESR limit to ensure it aligns with your oscillator circuit's drive level constraints. Verify that the 18 pF load capacitance matches the external capacitors specified in your schematic.

Crystals Part Context

This part belongs to the 7B series of surface-mount crystals from FTS, which are characterized by their small footprint and reliability. The 7B series is widely used in portable devices and industrial equipment where space constraints and timing accuracy are critical. This specific model provides a common frequency point for multimedia synchronization tasks.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The source indicates the part is obsolete and no longer manufactured. Users should consult FTS directly for current equivalent recommendations or verify cross-compatibility with other 14.7456 MHz crystals meeting identical electrical specifications.
