18QHTF21-3.2753-PD

Oscillators Overview

The 18QHTF21-3.2753-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 3.2753 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, designed for surface-mount assembly.

Oscillators Feature Summary

• LVCMOS output interface for digital compatibility
• Integrated standby mode for power reduction
• Compact 4-SMD no-lead surface mount footprint

Oscillators Applications

• Clock signal generation for low-frequency digital circuits
• Real-time clock applications requiring precise timing
• Embedded systems with strict space constraints

Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the power-down feature and '1.8V' voltage rating against the official datasheet. Ensure the 4-SMD no-lead package matches the PCB land pattern requirements. Confirm the 3.2753 MHz frequency tolerance specifications meet the target system's timing accuracy needs before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-power, small-footprint oscillator is required for 1.8V logic systems. The LVCMOS output ensures direct interfacing with compatible microcontrollers without additional level shifting. Consider the standby capability if power efficiency is critical. Verify that the 2.0x1.6 mm package fits within the available board area constraints.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small outline package. The 'PD' suffix indicates specific operational characteristics related to power management compared to standard variants.

Oscillators Replacement Considerations

Direct substitutes must match the 3.2753 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical parameters such as load capacitance and drive strength. Cross-reference with other manufacturers offering equivalent low-profile oscillators.
