18QHTF21-13.476-PD

Overview

The 18QHTF21-13.476-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 13.476 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features Enable/Disable control functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface mount applications.

Feature Summary

• Supports Enable/Disable control for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Operates on a low 1.8V supply voltage

Applications

• Battery-powered portable devices
• Digital signal processing systems
• Communication equipment requiring precise timing

Procurement Notes

Verify the specific suffix 'PD' against official Mercury Electronics documentation to confirm the presence of standby or power-down capabilities. Ensure the 1.8V supply requirement aligns with system design constraints before procurement. Cross-reference the 4-SMD package dimensions with PCB layout specifications.

Selection Notes

Select this component when a 13.476 MHz clock source with LVCMOS outputs is required. The 1.8V operating voltage makes it suitable for low-power designs. Consider the Enable/Disable feature if dynamic power management is necessary for the application environment.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'PD' suffix likely indicates specific power control features distinct from other variants in the lineup.

Replacement Considerations

Direct substitutes include other 13.476 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications before substitution.
