18QHTF21-59.648-OE

Overview

The 18QHTF21-59.648-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 59.648 MHz. It utilizes LVCMOS output logic and supports a supply voltage of 1.8V with enable/disable functionality. The component features a frequency stability of ±50ppm and operates within a temperature range of -40°C to 85°C. Maximum supply current is 23mA. It is housed in a 4-SMD, No Lead surface mount package.

Feature Summary

• Supports enable/disable control for power management
• LVCMOS output logic interface
• Surface mount construction with no lead design

Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Procurement Notes

Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm environmental compliance and packaging details. Ensure the 1.8V supply requirement aligns with system design constraints. Cross-reference the 4-SMD no-lead package dimensions with PCB footprint libraries to prevent assembly errors during procurement and integration phases.

Selection Notes

Select this model when a 59.648 MHz reference is required with low power consumption due to its 1.8V operation. Consider the ±50ppm stability for applications tolerant of moderate frequency drift. The enable/disable feature makes it suitable for battery-powered devices requiring active power states. Verify thermal requirements against the -40°C to 85°C operational range.

Part Context

This oscillator belongs to the QHTF series from Mercury Electronics, a supplier specializing in quartz crystals and timing solutions. The series typically offers various frequencies and voltages. This specific part represents a standard XO variant designed for compact electronic assemblies requiring precise timing signals in consumer or industrial electronics.

Replacement Considerations

The 18QHTF21-59.648-PD is a documented alternative from the same manufacturer. Verify if the PD suffix denotes different packaging or environmental standards compared to the OE suffix before substitution.
