18QHTF21-33.400-PD

Oscillators Overview

The 18QHTF21-33.400-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 33.4 MHz and utilizes LVCMOS output logic. 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 2.0mm x 1.6mm. This component is designed for applications requiring precise timing signals within a small form factor.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode to reduce power consumption
• Compact surface-mount package suitable for space-constrained designs

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontrollers and processors

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the input thresholds of the receiving components to ensure signal integrity.

Oscillators Selection Notes

Select this oscillator when a low-profile 2016 SMD footprint is required for 33.4 MHz timing. Consider the 1.8V supply constraint and the availability of the standby feature for power-sensitive applications. Compare performance metrics such as jitter and stability if available in the datasheet against alternative frequencies or packages from the same manufacturer family.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and output types in a standardized 4-SMD no-lead package. The 'PD' suffix likely indicates a specific pin configuration or packaging variant consistent with the manufacturer's ordering nomenclature for this form factor.

Oscillators Replacement Considerations

Direct replacements must match the 33.4 MHz frequency, LVCMOS output, 1.8V supply, and 2016 SMD package. Verify pinout compatibility and electrical characteristics with other manufacturers offering similar surface-mount oscillators. Cross-reference with other Mercury parts in the 18QHTF21 series for potential drop-in alternatives.
