18QHTF21-32.956-PD

Oscillators Overview

The 18QHTF21-32.956-PD is a 32.956 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates at a supply voltage of 1.8V. The device features a Standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package. This component serves as a standard clock source for electronic circuits requiring precise frequency generation with low power consumption capabilities.

Oscillators Feature Summary

• Generates a stable 32.956 MHz clock signal using LVCMOS logic levels
• Operates on a single 1.8V power supply rail
• Includes standby control capability to reduce power consumption when not in use
• Designed in a small surface-mount package suitable for space-constrained applications

Oscillators Applications

• Portable consumer electronics requiring low-power clock sources
• Embedded systems utilizing LVCMOS-compatible processors
• Communication modules needing precise timing references
• Industrial control boards with strict size limitations

Oscillators Procurement Notes

Verify the specific suffix PD indicates the Standby function against the official datasheet. Confirm the operating temperature range matches your environmental requirements. Ensure the 1.8V supply voltage aligns with your system design. Check the 4-SMD package dimensions for PCB layout compatibility. Validate that the LVCMOS output swing meets your receiver input thresholds.

Oscillators Selection Notes

Choose this model when a 32.956 MHz frequency is required alongside low voltage operation. The standby feature makes it suitable for battery-powered devices where power efficiency is critical. Compare the 4-SMD footprint against available board space. Consider the LVCMOS interface compatibility with downstream logic components. Evaluate thermal performance within the specified operating temperature range.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency generation solutions. The manufacturer specializes in quartz crystal products with decades of industry experience. The 18QHTF21 prefix likely denotes the package type and series characteristics. Other variants in this family may offer different frequencies or voltage levels.

Oscillators Replacement Considerations

The 18QHTF21-32.956-OE offers similar electrical specifications but uses an Enable/Disable control scheme instead of Standby. Verify if the control logic difference impacts your circuit design. Both parts share the same frequency and package type. Cross-reference pinouts to ensure compatibility during substitution.
