Applications

• Microcontroller clock sources requiring standard frequencies
• Communication interface circuits utilizing 16.384 MHz signaling
• Industrial control systems requiring reliable timing references

Procurement Notes

Verify the specific package variant when ordering, as bulk and tape/reel options exist under similar part numbers. Confirm that the 50 Ohm ESR specification aligns with the oscillator circuit design requirements. Ensure the 16.384 MHz frequency matches the target system clock needs. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate the 18 pF load capacitance against the PCB trace capacitance calculations.

Selection Notes

Select this component when a 16.384 MHz fundamental frequency is required for digital logic or communication protocols. The 50 Ohm ESR and 18 pF load capacitance must match the host oscillator circuit specifications to ensure stable startup and oscillation. Consider the 4-SMD package size for board layout constraints. Evaluate the ±20 ppm tolerance against the system's frequency accuracy requirements. Compare the -40°C to +85°C range against the operational environment limits.

Part Context

This crystal belongs to the general quartz crystal category from IQD Frequency Products, designed for surface mount technology. It serves as a passive frequency control element providing a stable reference signal. The 16.384 MHz frequency is commonly used in binary-based digital systems due to its divisibility into standard baud rates and clock speeds. It differs from oscillators by requiring an external active circuit to generate a square wave output.
