18QHTF21-7.32728-OE

Overview

The 18QHTF21-7.32728-OE is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.32728 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable/disable functionality for power optimization
• Compact 4-SMD no-lead surface mount package

Applications

• Portable electronic devices requiring low power consumption
• Communication equipment utilizing standard clock signals
• Embedded systems needing precise timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics to validate electrical characteristics and reliability standards for your specific application environment.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6mm package makes it ideal for space-constrained designs. Consider the enable/disable feature if power management during idle states is critical. Compare alternative frequencies if the exact 7.32728 MHz value does not match your system clock needs.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various standard frequencies in a unified compact form factor. The '-OE' suffix indicates the inclusion of an enable pin, distinguishing it from basic versions without control inputs. This family targets consumer electronics and industrial applications requiring reliable quartz-based timing.

Replacement Considerations

Direct substitutes must match the 7.32728 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent enable/disable functionality. Check for compatible load capacitance and drive strength specifications. Consult manufacturer cross-reference lists for verified alternatives ensuring identical pinout and electrical performance.
