18QHTF21-17.734-PD

Oscillators Overview

The 18QHTF21-17.734-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 17.734 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V for energy-efficient applications
• Integrates standby functionality to reduce power consumption during idle periods
• Utilizes LVCMOS output logic for compatibility with digital interfaces

Oscillators Applications

• Computing systems requiring precise clock signals
• Data communication equipment
• Consumer electronics devices

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 4-SMD no-lead package footprint matches the target PCB design. Ensure the 1.8V supply rail meets the current requirements for the LVCMOS outputs. Cross-reference the part number suffix to confirm the presence of the standby feature.

Oscillators Selection Notes

Select this component when a small form factor is required alongside low-power standby capabilities. The 1.8V supply requirement makes it suitable for modern low-voltage digital circuits. Consider the 2.0x1.6 mm package size for space-constrained designs. Verify that the LVCMOS output levels are compatible with the receiving logic inputs.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal and oscillator solutions. The manufacturer has decades of experience in frequency control products. This series typically offers standard oscillators designed for computing and general electronic applications.

Oscillators Replacement Considerations

Direct substitutes must match the 17.734 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Check if alternative manufacturers offer equivalent standby functionality.
