18QHTF21-34.300-PD

Oscillators Overview

The 18QHTF21-34.300-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 34.3 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Utilizes LVCMOS output logic
• Features a compact surface-mount package

Oscillators Applications

• General digital timing circuits

• Portable electronic devices due to low voltage requirements

Oscillators 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 no-lead package footprint matches your PCB layout specifications. Check for any RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a stable 34.3 MHz clock source is needed with minimal power consumption. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the physical size constraints as the 2.0x1.6mm package is suitable for space-sensitive designs. Evaluate the need for power-down capabilities if battery life is a critical factor.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, designed for general-purpose timing applications. The 'PD' suffix typically indicates the inclusion of a power-down pin or function. The product line focuses on providing reliable quartz-based oscillators in small form factors for modern electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 34.3 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators with identical electrical specifications.
