18QHTF21-28.880-PD

Oscillators Overview

The 18QHTF21-28.880-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 28.88 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage 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 function to reduce power consumption during idle periods
• Utilizes a leadless SMD package for automated surface-mount assembly

Oscillators Applications

• Digital clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring precise synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure the correct pinout and electrical specifications match your design requirements. Confirm that the 1.8V supply voltage aligns with your system's power rails before integration. Check the latest datasheet for any updates regarding the standby control mechanism and operating temperature range to guarantee reliable performance in your intended environment.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard 28.88 MHz frequency. The LVCMOS output is suitable for direct interfacing with digital logic circuits without additional level shifting. Consider the 4-SMD no-lead package for space-constrained designs where surface-mount technology is preferred over through-hole mounting solutions.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The model number indicates a 28.88 MHz frequency variant within the 18QHTF21 family. These oscillators are designed for general-purpose timing applications, offering a balance between performance and cost-effectiveness for consumer and industrial electronics.

Oscillators Replacement Considerations

Consult official substitution lists from Mercury Electronics for compatible alternatives. Ensure any replacement matches the 28.88 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify that the substitute component supports the same standby functionality and meets the required operating temperature specifications.
