18QHTF21-61.049-OE

Overview

The 18QHTF21-61.049-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 61.049 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a 4-SMD, No Lead package.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Designed as a standard crystal oscillator with no lead surface mount packaging

Applications

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

Procurement Notes

Verify the specific part number suffix against official Mercury Electronics documentation to confirm voltage and frequency specifications. Ensure the 1.8V supply requirement aligns with the target system design. Confirm the 4-SMD package dimensions match the PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a 61.049 MHz clock source is required with LVCMOS outputs. The 1.8V operating voltage must be compatible with the host system's power rails. Consider the enable/disable feature if dynamic power control is necessary for the application environment.

Part Context

This model belongs to the QHTF series of surface mount oscillators from Mercury Electronics. The series typically offers standard frequency options with compact footprints suitable for space-constrained electronic designs. The 'OE' suffix may indicate specific ordering or configuration details defined by the manufacturer.

Replacement Considerations

Direct substitutes require matching 61.049 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics with alternative manufacturers before substitution.
