18QHTF21-4.9152-OE

Oscillators Overview

The 18QHTF21-4.9152-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 4.9152 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 1.6mm x 1.2mm x 0.4mm.

Oscillators Feature Summary

• Supports Enable/Disable functionality for active power control
• Utilizes LVCMOS output interface for digital compatibility
• Designed for low-profile surface-mount applications

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication modules needing precise timing references
• Embedded systems utilizing LVCMOS logic standards

Oscillators Procurement Notes

Verify the specific suffix 'OE' confirms the Enable/Disable feature rather than 'PD' for Power Down or no suffix for standard operation. Confirm the 1.8V supply voltage requirement matches the target circuit design. Ensure the 4-SMD No Lead package footprint aligns with the PCB layout specifications to prevent assembly errors.

Oscillators Selection Notes

Select this component when an enable/disable pin is required for power management in LVCMOS circuits. Compare against the 18QHTF21-4.9152-PD if a standby mode is preferred over active disable control. Ensure the operating temperature range meets the environmental requirements of the final application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a supplier specializing in quartz crystals and oscillators. The series offers various frequencies and package options. The -OE suffix specifically denotes the inclusion of an enable/disable control signal, differentiating it from standard or power-down variants within the same family.

Oscillators Replacement Considerations

The 18QHTF21-4.9152-PD serves as a functional alternative if a power-down standby mode is acceptable instead of enable/disable control. Both share the same frequency, package, and voltage specifications. Verify that the control logic polarity matches the system design before substitution.
