18QHTF21-7.382-OE

Overview

The 18QHTF21-7.382-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.382 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 2.0mm x 1.6mm. The component supports an operating temperature range suitable for general electronic applications.

Feature Summary

• Integrates enable/disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Employs a leadless SMD package for surface mount assembly

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper solder joint formation and mechanical stability during operation.

Selection Notes

Select this component when a low-voltage 1.8V clock source is required for space-constrained designs. The LVCMOS output is appropriate for standard digital logic families. Consider the small 2.0x1.6mm footprint if board real estate is limited. Verify that the enable pin can be effectively utilized within the system architecture to manage power consumption during idle states.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. Mercury Electronics is a manufacturer specializing in frequency control products, including crystals and oscillators, with a history of production in Taiwan. This specific model represents a fixed-frequency variant within that product line.

Replacement Considerations

Direct replacements must match the 7.382 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Cross-reference with other manufacturers offering similar small-footprint XO components. Ensure electrical parameters such as phase noise and jitter meet or exceed the original specifications for equivalent performance.
