18QHTF21-15.620-PD

Oscillators Overview

The 18QHTF21-15.620-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 15.62 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage power consumption during inactive periods. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise clock signals.

Oscillators Feature Summary

• Supports low-voltage operation with 1.8V supply requirement
• Integrates standby mode for power management
• Provides LVCMOS output signal compatibility

Oscillators Applications

• Digital signal processing systems

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V operating voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper assembly and electrical connection.

Oscillators Selection Notes

Select this model when a stable 15.62 MHz reference is required for LVCMOS-compatible digital circuits. Consider the 1.8V supply constraint and the availability of the power-down feature for energy-efficient designs. Evaluate the physical dimensions of the 4-SMD package to ensure it fits within the designated area on the printed circuit board without interfering with adjacent components.
