18QHTF21-14.300-PD

Oscillators Overview

The 18QHTF21-14.300-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 14.3 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to reduce consumption during idle periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is suitable for applications requiring precise timing signals in low-voltage digital systems.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power management
• Compact surface-mount package design

Oscillators Applications

• General purpose clock signal generation
• Low voltage digital circuit timing
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's current datasheet to ensure compatibility with your board layout. Confirm that the 1.8V supply requirement aligns with your system's power rails. Check for any recent updates to the RoHS compliance status or lead-free specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 14.3 MHz reference is required for LVCMOS compatible circuits. Ensure the PCB footprint matches the 2.0x1.6mm SMD no-lead package dimensions. Consider the 1.8V operating voltage constraint and verify that the standby feature meets your power efficiency requirements compared to other available oscillator families.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies within the same physical footprint. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous operation variants within the same package family.

Oscillators Replacement Considerations

Direct replacements must match the 14.3 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility, specifically the power-down control pin assignment, before substituting with components from other manufacturers.
