18QHTF21-16.31725-PD

Oscillators Overview

The 18QHTF21-16.31725-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 16.31725 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. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic levels
• Includes Standby or Power Down functionality for energy management
• Utilizes a small form factor 4-SMD No Lead surface mount package

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication equipment utilizing standard clock signals
• Embedded systems needing precise timing references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is mandatory for the target application. The choice is appropriate for space-constrained designs due to the 2.0x1.6mm package size. Consider the LVCMOS output compatibility with your receiving digital logic. The standby feature makes it suitable for battery-powered applications where power efficiency is critical.
