18QHTF21-35.9991-OE

Oscillators Overview

The 18QHTF21-35.9991-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 35.9991 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable/disable functionality for power management
• Utilizes a low-profile surface-mount package design

Oscillators Applications

• General clock signal generation in electronic circuits
• Embedded systems requiring precise timing references
• Consumer electronics utilizing standard crystal oscillators

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the Enable/Disable pin configuration matches your control logic to guarantee proper operation during standby or active states.

Oscillators Selection Notes

Select this component when a standard XO with LVCMOS outputs is required at approximately 36 MHz. The 1.8V operating voltage makes it suitable for low-power applications. Consider the 2.0x1.6mm footprint for space-constrained designs. Verify thermal performance within the specified operating temperature range for your specific environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small SMD package. The suffix -OE typically denotes the Enable/Disable feature set. This series provides alternatives to larger through-hole or different surface-mount packages found in other oscillator families.

Oscillators Replacement Considerations

Direct replacements must match the 35.9991 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as jitter and phase noise if critical. Consult manufacturer cross-reference lists for verified substitutes.
