18QHTF21-14.08919-PD

Oscillators Overview

The 18QHTF21-14.08919-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 14.08919 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and features a Standby (Power Down) function for energy management. It is housed in a 4-SMD, No Lead package with dimensions of 7.0mm x 5.0mm.

Oscillators Feature Summary

• Provides a miniaturized frequency source suitable for compact electronic systems
• Integrates a standby mode to enable power down capabilities
• Utilizes LVCMOS output logic for standard digital interface compatibility

Oscillators Applications

• Compact electronic systems requiring precise timing
• Portable devices utilizing low voltage operation
• Digital circuits needing standard clock signals

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 7.0x5.0mm footprint matches your PCB layout constraints. Check for any specific handling instructions related to the no-lead SMD package during assembly.

Oscillators Selection Notes

Select this component when a 14.08919 MHz clock signal is required with low voltage operation. Consider the physical size constraints as the 7.0x5.0mm package is larger than some smaller alternatives. Evaluate the need for the standby feature if power efficiency is a priority. Ensure the LVCMOS output is compatible with the receiving logic inputs of your target application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same package form factor. The series includes options like 8.000 MHz and 51.200 MHz variants. The 'PD' suffix indicates the inclusion of a power down pin or functionality. This series is designed for applications requiring reliable frequency control in space-constrained environments.

Oscillators Replacement Considerations

Direct substitutes include other 14.08919 MHz oscillators from Mercury Electronics in the same package, such as the 18QHTF21-14.08919 without the PD suffix if power down is not needed. Cross-manufacturer replacements must match the 1.8V supply, LVCMOS output, and 7.0x5.0mm footprint precisely.
