18QHTF21-32.2123-PD

Oscillators Overview

The 18QHTF21-32.2123-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 32.2123 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down standby function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes power-down standby capability to reduce consumption
• Utilizes quartz crystal technology for stable oscillation

Oscillators Applications

• General clock signal generation in electronic circuits
• Data communication systems requiring precise timing
• Embedded systems utilizing low-voltage logic interfaces

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 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific handling instructions related to the sensitive quartz component.

Oscillators Selection Notes

Select this model when a 32.2123 MHz reference is required for LVCMOS-compatible devices. The 1.8V operating voltage makes it suitable for modern low-power applications. Consider the small 2.0x1.6mm form factor for space-constrained designs. The power-down feature adds flexibility for battery-operated or energy-efficient systems.

Oscillators Part Context

This component belongs to the Mercury Electronics XO series, designed for surface-mount applications. The '18' prefix likely indicates the 1.8V supply requirement, while 'QHTF21' denotes the specific package and performance class. The '-PD' suffix confirms the inclusion of a power-down control pin or function within the oscillator module.

Oscillators Replacement Considerations

Direct substitutes must match the 32.2123 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify compatibility with existing power-down control signals. Cross-reference pinouts and electrical characteristics to ensure seamless integration without circuit modification.
