18QHTF21-2.457-PD

Oscillators Overview

The 18QHTF21-2.457-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 2.457 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V 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 low-power standby operation for energy efficiency
• Provides stable LVCMOS output signals
• Utilizes a compact surface-mount package design

Oscillators Applications

• Battery-powered portable devices
• General-purpose digital timing circuits
• Embedded systems requiring low-voltage clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply rail is stable and within the specified operating range to maintain signal integrity. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to avoid assembly issues.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and a standard XO with LVCMOS outputs is required. Consider the 2.457 MHz frequency specifically for applications needing this exact clock rate. Evaluate the need for standby functionality if power management is a priority in the target system design.
