18QHTF21-28.480-PD

Oscillators Overview

The 18QHTF21-28.480-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 28.48 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and supporting a standby or power-down mode to reduce energy consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated standby function for power management
• Compact surface-mount package design

Oscillators Applications

• General-purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability.

Oscillators Selection Notes

Select this component when a precise 28.48 MHz reference is required with minimal power consumption. The LVCMOS output ensures direct interfacing with standard digital logic without additional level shifting. Consider the 1.8V operation if your system prioritizes low-voltage efficiency over higher drive capabilities found in other oscillator families.
