18QHTF21-24.756-PD

Oscillators Overview

The 18QHTF21-24.756-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 24.756 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down standby function 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-voltage digital systems.

Oscillators Feature Summary

• Supports LVCMOS output logic for direct interface with digital circuits
• Includes a power-down standby mode to reduce current consumption
• Utilizes a small form factor 4-SMD no lead package for space-constrained designs

Oscillators Applications

• Digital signal processing systems requiring stable clock sources
• Communication equipment utilizing LVCMOS compatible interfaces
• Portable electronic devices where low voltage operation is critical

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Ensure that the 1.8V supply voltage aligns with your power rail specifications. Confirm that the LVCMOS output swing is compatible with the input thresholds of the receiving logic components. Check the datasheet for operating temperature range limitations relevant to your environment.

Oscillators Selection Notes

Select this oscillator when a 24.756 MHz frequency is required with LVCMOS outputs. Consider the 1.8V supply constraint and the need for a power-down feature. Evaluate the 2.0x1.6mm footprint against available PCB space. Compare performance metrics such as phase noise and stability if available in official documentation against alternative frequencies or packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies with standardized LVCMOS outputs and low voltage operation. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct replacements must match the 24.756 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility and electrical characteristics. Consult manufacturer cross-reference lists for confirmed substitutes.
