18QHTF21-37.209375-OE

Oscillators Overview

The 18QHTF21-37.209375-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 37.209375 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features an enable/disable control function for power management. It is housed in a compact 4-SMD, no-lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Generates stable clock signals using LVCMOS output logic
• Supports active low power consumption via enable/disable control
• Designed for surface-mount integration with a leadless package

Oscillators Applications

• Timing and clock signal generation in electronic devices
• Digital circuit synchronization systems
• Communication equipment requiring precise frequency references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 37.209375 MHz reference is required with low-voltage operation. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the enable/disable feature if power efficiency is critical for the application. The small form factor makes it suitable for space-constrained designs where traditional through-hole oscillators cannot fit.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which specializes in quartz-based timing solutions. Mercury Electronic Ind. Co., Ltd. has extensive experience in manufacturing frequency control products, including crystals and oscillators. This specific model represents their capability to provide customized or standard frequencies in compact surface-mount packages for modern electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 37.209375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before swapping. Generic replacements may differ in operating temperature range or startup time.
