18QHTF21-50.224667-PD

Overview

The 18QHTF21-50.224667-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 50.224667 MHz with an LVCMOS output logic level. The device functions on a 1.8V supply voltage and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Features LVCMOS output interface
• Includes standby and power-down capabilities

Applications

• General clock signal generation
• Low-power electronic systems
• Compact digital circuitry requiring precise timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. 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 constraints to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a standard XO with LVCMOS output is required for 1.8V applications. Consider the 2.0x1.6 mm form factor for space-constrained designs. Evaluate the need for power-down functionality to manage system energy consumption effectively during idle states compared to continuous operation alternatives.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a manufacturer specializing in frequency control products. The series typically offers various frequencies within a small SMD package, catering to modern electronics that demand miniaturization and low power consumption while maintaining reliable clock signals.

Replacement Considerations

Direct substitutes may include other 1.8V LVCMOS oscillators in 4-SMD packages with similar frequencies. Verify pin compatibility and thermal characteristics. Cross-reference with Mercury’s broader catalog for alternative frequencies if exact match is unavailable.
