18QHTF21-124.870-OE

Overview

The 18QHTF21-124.870-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 124.87 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 suitable for surface mount applications.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable control functionality for power management
• Designed for surface mount installation with no-lead SMD packaging

Applications

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

Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current datasheet to confirm pinout and electrical characteristics. Ensure the 1.8V supply requirement aligns with the target system design. Confirm the 4-SMD no-lead package dimensions match the PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a 124.87 MHz clock source with LVCMOS outputs is required. The 1.8V operating voltage makes it suitable for low-power digital systems. The enable/disable feature allows for dynamic power control. Verify that the surface mount package type fits the assembly constraints.

Part Context

This part belongs to the 18QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 18QHTF21 variant specifically denotes the package style and operational parameters defined by the manufacturer for this product line.

Replacement Considerations

Direct substitutes include other 18QHTF21 models with compatible frequencies such as 18QHTF21-124.870-PD, though note that the PD suffix may indicate different control features like standby mode instead of enable/disable. Always verify electrical specifications before substitution.
