18QHTF21-7.373-PD

Overview

The 18QHTF21-7.373-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.373 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and supports a standby or power-down mode for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise timing signals within low-power electronic systems.

Feature Summary

• Supports standby and power-down modes for efficient power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Features a compact 4-SMD no-lead surface mount package

Applications

• Low-power portable electronic devices
• Digital communication equipment
• Microcontroller clock sources

Procurement Notes

Verify the specific frequency tolerance and stability requirements against your system design before procurement. Confirm that the 1.8V operating voltage aligns with your power supply architecture. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Check for any specific environmental ratings required for your application environment.

Selection Notes

Select this oscillator when a 7.373 MHz reference signal is needed with low voltage operation. Consider the LVCMOS output compatibility with your target digital logic family. Evaluate the need for power-down functionality to extend battery life in portable designs. Verify that the physical footprint matches your assembly capabilities.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a small form factor. The series typically includes models like 18QHTF21-37.300-PD and 18QHTF21-8.000-PD, sharing similar electrical characteristics and packaging but differing in nominal frequency. The 'PD' suffix indicates the inclusion of power-down capability.

Replacement Considerations

Direct replacements must match the 7.373 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Other Mercury models in the same series may offer different frequencies but share the same interface and form factor.
