18QHTF21-41.625-PD

Oscillators Overview

The 18QHTF21-41.625-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 41.625 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode capability for power management
• Utilizes a leadless SMD package for surface-mount integration

Oscillators Applications

• General purpose timing reference for electronic circuits
• Clock signal generation in data communication systems

Oscillators Procurement Notes

Verify the specific operating voltage and load requirements against the target circuit design before procurement. Confirm that the 1.8V supply specification aligns with the system power rails. Ensure the 4-SMD no-lead footprint matches the PCB layout constraints. Check for RoHS compliance status if required by project specifications. Validate the standby function availability if low-power operation is critical to the application.

Oscillators Selection Notes

Select this component when a stable 41.625 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V supply constraint and ensure the system can provide this voltage level. The standby feature should be evaluated if power efficiency during idle states is a priority. Verify that the small form factor fits within the available board space constraints.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The 18QHTF21 prefix indicates a specific package and performance class within their lineup. These oscillators are designed for applications requiring reliable quartz-based timing with minimal footprint.

Oscillators Replacement Considerations

Direct substitutes must match the 41.625 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics before substitution.
