18QHTF21-33.33333-PD

Oscillators Overview

The 18QHTF21-33.33333-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 33.33333 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down mode capability. It is housed in a compact 4-SMD, no lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Includes standby or power-down functionality for energy management
• Utilizes a small form-factor 4-SMD no-lead package design

Oscillators Applications

• General-purpose clock signal generation in electronic circuits
• Timing reference sources for digital systems
• Embedded devices requiring stable frequency standards

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Check for any specific environmental operating temperature ranges required by your application to ensure reliability under all conditions.

Oscillators Selection Notes

Select this component when a precise 33.33333 MHz clock source is needed with low power consumption. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency during idle periods is a priority. The small package size makes it suitable for space-constrained designs where larger oscillators cannot be accommodated.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 4-SMD footprint. The series provides consistent performance characteristics across different frequency options, allowing designers to maintain uniform board layouts while adjusting timing parameters. The 'PD' suffix typically indicates specific packaging or handling variations defined by the manufacturer.

Oscillators Replacement Considerations

Direct replacements must match the 33.33333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as phase noise and jitter if critical. Consult official substitution lists from Mercury Electronics for validated alternatives.
