18QHTF21-27.200-PD

Oscillators Overview

The 18QHTF21-27.200-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 27.2 MHz. It utilizes LVCMOS output logic and supports 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, designed for surface mount applications.

Oscillators Feature Summary

• Standard XO configuration with LVCMOS output
• Integrated standby (power down) capability
• Compact 4-SMD no lead surface mount package

Oscillators Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current datasheet to ensure compatibility with required specifications. Confirm that the 1.8V supply voltage aligns with the target system design before procurement. Check for any recent updates to the 4-SMD package dimensions or thermal characteristics.

Oscillators Selection Notes

Select this component when a low-profile surface mount oscillator is required for 27.2 MHz applications. Ensure the system design accommodates the 1.8V supply requirement and LVCMOS interface. Consider the standby feature if power management during idle states is a priority for the application.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD oscillator series, which includes various frequencies and packages. The 18QHTF21 series typically offers standard performance levels suitable for general-purpose digital electronics. It is distinct from TCXO or VCXO variants within the same product family.

Oscillators Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify pinout compatibility and electrical parameters such as frequency tolerance and load capacitance before replacing with alternative brands.
