18QHTF21-14.318-PD

Oscillators Overview

The 18QHTF21-14.318-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 14.318 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) control function to manage power consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated Standby (Power Down) functionality
• Compact 4-SMD No Lead surface-mount package

Oscillators Applications

• General-purpose digital timing circuits
• Embedded systems requiring low-power oscillators
• Consumer electronics with space constraints

Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the Power Down feature against the official datasheet. Ensure the operating temperature range meets your application requirements. Confirm that the 1.8V supply voltage aligns with your system design before procurement.

Oscillators Selection Notes

Select this component when a 14.318 MHz frequency is required with LVCMOS outputs. Consider the 1.8V supply constraint and the need for a standby mode. The small 2.0x1.6mm footprint makes it suitable for dense PCB layouts compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 2.0x1.6mm SMD package. The series typically supports LVCMOS outputs and includes options for power-down capabilities, providing flexibility for different timing needs in compact electronic designs.

Oscillators Replacement Considerations

Direct substitutes must match the 14.318 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD No Lead package. Verify pinout compatibility and electrical specifications such as load capacitance and drive strength before substitution.
