18QHTF21-42.1375-PD

Oscillators Overview

The 18QHTF21-42.1375-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 42.1375 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation with integrated standby capability
• Delivers stable LVCMOS signal outputs for digital circuits
• Utilizes a leadless surface-mount package for automated assembly

Oscillators Applications

• General-purpose clock generation for embedded systems
• Timing reference for data communication interfaces
• Synchronization source for consumer electronics devices

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 42.1375 MHz specification. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package dimensions are compatible with the PCB footprint. Check for any specific operating temperature range requirements before finalizing the order.

Oscillators Selection Notes

Select this component when a standard LVCMOS clock signal is required at 42.1375 MHz. Consider the 1.8V supply constraint and the need for a standby feature. Evaluate the 4-SMD form factor against available board space. Compare performance against other Mercury oscillators if different frequencies or voltages are needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has decades of experience in producing crystals and oscillators. This series typically offers standard specifications suitable for mass production environments.

Oscillators Replacement Considerations

Direct substitutes must match the 42.1375 MHz frequency, LVCMOS output, and 1.8V supply. Verify pinout compatibility for the 4-SMD no-lead package. Cross-reference with other Mercury models in the same series for potential equivalents.
