18QHTF21-93.000-PD

Overview

The 18QHTF21-93.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 93 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a power-down standby function for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated power-down standby mode to reduce consumption
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing systems
• Communication equipment timing
• Embedded control circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 2.0x1.6 mm footprint matches your PCB layout constraints. Check for any specific handling instructions regarding the no-lead SMD package during assembly.

Selection Notes

Select this oscillator when a 93 MHz clock signal is required with low voltage operation. Consider the LVCMOS output level if interfacing with 1.8V logic families. The small form factor makes it suitable for space-constrained designs. Evaluate the need for the power-down feature if battery life or thermal management is a priority in the application environment.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 2.0x1.6 mm package. The series typically supports LVCMOS outputs and 1.8V operation. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-output variants in the same physical footprint family.

Replacement Considerations

Direct replacements must match the 93 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6 mm package. Verify that substitute components also include the power-down functionality if required. Cross-reference pinouts to ensure compatibility with existing PCB traces.
