18QHTF21-33.868-OE

Oscillators Overview

The 18QHTF21-33.868-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 33.868 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The unit maintains a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Supports active enable and disable control for efficient power management
• Delivers standard LVCMOS output signals compatible with digital interfaces
• Designed for compact surface-mount applications with a leadless SMD footprint

Oscillators Applications

• Portable consumer electronics requiring low power consumption
• Embedded systems utilizing LVCMOS-compatible processors
• Industrial control modules operating in extended temperature ranges

Oscillators Procurement Notes

Verify the specific suffix 'OE' corresponds to the 1.8V supply voltage and enable/disable feature set. Confirm that the 4-SMD no-lead package dimensions align with PCB layout constraints. Ensure the ±50ppm stability meets system timing requirements. Cross-reference the manufacturer's latest datasheet for reflow soldering profiles and handling precautions specific to this Mercury Electronics component.

Oscillators Selection Notes

Select this oscillator when a 33.868 MHz clock source is required with strict size limitations due to its 2.0x1.6 mm form factor. Choose the 1.8V variant if the target circuit operates on low-voltage rails rather than 3.3V. Consider the enable pin requirement; if constant operation without control signals is needed, verify if alternative suffixes exist. The ±50ppm stability is suitable for general digital timing but may require tighter specifications for high-precision communication interfaces.

Oscillators Part Context

This component belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies and voltage options, including 3.3V variants like the 18QHTF21-33.868-PD. The 'OE' suffix typically denotes specific electrical characteristics such as voltage and control features within this product line.

Oscillators Replacement Considerations

Direct substitutes must match the 33.868 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify compatibility with the enable/disable function. Generic replacements should be sourced only from manufacturers providing identical pinout and thermal specifications.
