18QHTF21-75.585-OE

Overview

The 18QHTF21-75.585-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 75.585 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. A key functional characteristic is the inclusion of an enable/disable control pin, allowing for power management in system designs. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• Integrates enable/disable functionality for active power control
• Delivers LVCMOS compatible digital output signals
• Operates on a single 1.8V power supply rail

Applications

• High-performance digital signal processing systems
• Communication equipment requiring precise clock timing
• Embedded systems with strict power consumption constraints

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power architecture. Ensure the 4-SMD no-lead package dimensions fit within your PCB footprint constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliable assembly.

Selection Notes

Select this component when a stable 75.585 MHz reference is required for LVCMOS interfaces. The enable feature makes it suitable for battery-operated or power-sensitive devices. Consider the 1.8V operating voltage to match low-power logic families. Evaluate the small form factor against available board space. Compare performance metrics such as phase noise and stability if multiple oscillator options are available for the target application.

Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes a specific packaging or tape-and-reel configuration. Mercury Electronics specializes in frequency control products, including crystals and oscillators, serving global electronics markets with precision timing solutions.

Replacement Considerations

Direct replacements must match the 75.585 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics. Consult manufacturer cross-reference lists for verified substitutes.
