18QHTF21-38.7853-OE

Oscillators Overview

The 18QHTF21-38.7853-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 38.7853 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm by 1.6mm. The component is designed for surface-mount applications within specified operating temperature ranges.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features enable and disable control functionality for power management
• Utilizes quartz technology for stable frequency generation

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference sources for embedded systems
• Digital communication interfaces requiring precise frequency standards

Oscillators Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current documentation to ensure correct configuration. Confirm that the 1.8V supply voltage aligns with the target system design requirements. Check the operating temperature range specifications to ensure suitability for the intended environmental conditions before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Ensure the application does not require differential signaling, as this model provides single-ended LVCMOS outputs only.

Oscillators Part Context

This oscillator belongs to the H21 series of SMD oscillators from Mercury Electronic. The series is characterized by quartz-based construction and surface-mount packaging. The part number indicates a specific frequency and voltage configuration within the company's standard oscillator product line.

Oscillators Replacement Considerations

Direct substitutes must match the 38.7853 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics with alternative manufacturers before substitution.
