18QHTF21-58.800-OE

Overview

The 18QHTF21-58.800-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 58.8 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control pin for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 3.2mm x 2.5mm. This component is designed for applications requiring precise clock signals in low-voltage digital circuits.

Feature Summary

• LVCMOS output logic for direct interface with digital components
• Integrated enable/disable functionality for power optimization
• Compact surface-mount package suitable for space-constrained designs

Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring stable clock sources

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 LVCMOS output swing is compatible with the input thresholds of the receiving device. Check the operating temperature range to ensure reliability under expected environmental conditions. Validate the package footprint matches your PCB layout constraints.

Selection Notes

Select this oscillator when a 58.8 MHz clock signal is required with low voltage operation. Consider the LVCMOS output type for compatibility with standard logic families. Evaluate the enable/disable feature if power saving during idle periods is necessary. Compare the 3.2x2.5mm package size against available board space. Assess the need for a standard XO versus more advanced options like TCXO based on stability requirements.

Part Context

This part belongs to the 18QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a similar form factor. The 'OE' suffix likely denotes the presence of an output enable pin. Mercury Electronics specializes in frequency control products, including crystals and oscillators, providing solutions for timing applications across multiple industries.

Replacement Considerations

Direct replacements must match the 58.8 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility, particularly the enable pin configuration. Check if alternative manufacturers offer equivalent specifications in the same footprint. Ensure thermal and electrical characteristics are comparable to maintain system performance.
