18QHTF21-58.6317-OE

Overview

The 18QHTF21-58.6317-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 58.6317 MHz with a supply voltage of 1.8V. The device features LVCMOS output logic and includes an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Integrated enable/disable functionality for power management
• LVCMOS output logic compatibility
• Compact surface-mount package design

Applications

• General clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's datasheet to confirm the presence of the enable pin and LVCMOS output characteristics. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm the 4-SMD no-lead package footprint matches the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise frequency stability at 58.6317 MHz. The enable feature makes it suitable for applications requiring power conservation during idle states. Consider the small 2.0x1.6mm footprint for space-constrained designs compared to larger oscillator packages.

Part Context

This part belongs to the QHTF series of high-frequency oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within similar small form factors. The '18' prefix indicates the 1.8V operating voltage, distinguishing it from other variants like the 2.5V or 3.3V versions in the same product line.

Replacement Considerations

Check for direct substitutes such as the 18QHTF21-58.6317-PD if pinout and package compatibility are verified. Other Mercury models with identical frequency and voltage but different output types may require circuit adjustments.
