18QHTF21-34.000-PD

Oscillators Overview

The 18QHTF21-34.000-PD is a 34.0 MHz crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co. Ltd. It utilizes LVCMOS output logic and operates at a supply voltage of 1.8V. The component features a power-down function via standby control. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy management
• Provides standard LVCMOS output signals

Oscillators Applications

• General electronic timing circuits
• Embedded system clock generation
• Portable device synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Oscillators Selection Notes

Select this model when a precise 34.0 MHz reference is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital systems. The integrated power-down feature allows for dynamic power management during idle periods. Consider the small 4-SMD package size if board real estate is limited compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down pin or function. These components are designed for applications requiring stable clock signals in compact form factors.

Oscillators Replacement Considerations

Direct substitutes must match the 34.0 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pin compatibility and electrical specifications before swapping. Other manufacturers may offer equivalent parts, but mechanical and electrical parameters must be identical.
