18QHTF21-16.005-PD

Oscillators Overview

The 18QHTF21-16.005-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 16.005 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated standby mode for power reduction
• Compact surface-mount form factor

Oscillators Applications

• General timing reference for embedded systems
• Clock source for microcontrollers
• Data communication interfaces requiring precise frequency stability

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet for the intended application environment.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint clock source is required. The LVCMOS output simplifies interfacing with standard digital logic families. Consider the standby feature if power efficiency is a critical design parameter. Compare alternative frequencies within the same series if the exact 16.005 MHz value is not strictly necessary for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various standard frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down capability. These components are designed for applications requiring stable clock signals in space-constrained electronic devices.

Oscillators Replacement Considerations

Direct substitutes may include other 16.005 MHz LVCMOS oscillators in a 2.0x1.6mm SMD package from different manufacturers, provided pinouts and electrical characteristics match. Verify that any replacement supports the 1.8V supply and standby functionality. Cross-reference the mechanical dimensions to ensure PCB compatibility.
