18QHTF21-123.870968-OE

Overview

The 18QHTF21-123.870968-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 123.870968 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features enable/disable functionality. It is housed in a compact 4-SMD, no lead package. The component exhibits a frequency stability of ±50ppm. This oscillator is designed for applications requiring precise timing signals within low-voltage digital systems.

Feature Summary

• Supports LVCMOS output logic for direct interface with digital circuits
• Includes enable and disable control pins for power management
• Utilizes a surface-mount 4-SMD no-lead package for automated assembly

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure compatibility with required voltage and load conditions. Confirm that the 1.8V supply requirement aligns with the target circuit design. Check for any recent updates to the frequency stability specifications or package dimensions prior to finalizing procurement orders.

Selection Notes

Select this component when a 123.870968 MHz clock source is required with LVCMOS compatibility. Ensure the system design supports the 1.8V operating voltage. Consider the ±50ppm stability requirement against the application's jitter tolerance. Verify that the 4-SMD footprint fits within the available PCB area constraints.

Part Context

This model belongs to the QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 18 prefix indicates the 1.8V supply variant. The part number structure follows the manufacturer's convention for specifying frequency and output type.

Replacement Considerations

Direct substitutes include the 18QHTF21-123.870968-PD variant, which shares similar electrical characteristics but may differ in packaging or ordering suffixes. Cross-reference with other 1.8V LVCMOS oscillators of the same frequency if availability is an issue.
