18QHTF21-24.5454-PD

Oscillators Overview

The 18QHTF21-24.5454-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.5454 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down (standby) control function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for applications requiring precise frequency generation in space-constrained environments.

Oscillators Feature Summary

• LVCMOS output interface for digital circuit compatibility
• Integrated power-down control for standby mode operation
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Precision timing circuits
• Compact electronic devices
• Digital signal processing systems

Oscillators Procurement Notes

Verify the exact specifications against the official datasheet from Mercury Electronic Ind. Co., Ltd. before integration. Confirm that the 1.8V supply voltage and LVCMOS output levels match your system requirements. Ensure the 2.0x1.6mm footprint aligns with your PCB layout constraints. Check for any specific handling or storage conditions required for quartz components.

Oscillators Selection Notes

Select this model when a 24.5454 MHz frequency is strictly required. The 1.8V operating voltage makes it suitable for low-power portable electronics. The power-down feature is essential for battery-operated devices needing extended standby times. Consider the small form factor if board space is limited. Verify temperature range requirements against application needs.

Oscillators Part Context

This part belongs to the QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltages. The 'PD' suffix indicates the power-down capability. Similar parts include the 18QHTF21-24.545454-OE which uses enable/disable control instead of power-down. The series supports both standard and spread-spectrum options.

Oscillators Replacement Considerations

The 18QHTF21-24.545454-OE is a related part but uses OE control rather than PD. Direct substitutes must match the 24.5454 MHz frequency, 1.8V voltage, and LVCMOS output. Verify pinout compatibility for the 4-SMD package. Ensure thermal characteristics are equivalent for the target environment.
