18QHTF21-42.5625-OE

Oscillators Overview

The 18QHTF21-42.5625-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 42.5625 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to prevent assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The enable/disable feature makes it suitable for battery-powered devices where power conservation is critical. Consider the small form factor if space constraints are a primary design driver for the target application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile oscillators. The series typically offers various frequency options within a standardized 4-pin SMD footprint. The 'OE' suffix likely denotes a specific tape-and-reel or packaging variant, though exact packaging details require datasheet confirmation.

Oscillators Replacement Considerations

Direct substitutes must match the 42.5625 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that any alternative component supports the enable/disable functionality if used in the original design. Cross-reference pinouts to ensure electrical compatibility without redesigning the PCB layout.
