18QHTF21-13.0625-PD

Overview

The 18QHTF21-13.0625-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 13.0625 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage range including 3.3V and features a standby (power down) function for energy management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.5x2.0mm, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Standard XO configuration with LVCMOS output interface
• Integrated standby mode for power reduction
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose digital timing circuits
• Communication equipment clock sources
• Embedded system microcontroller interfaces

Procurement Notes

Verify the specific operating voltage requirement against your circuit design, as datasheets indicate support for multiple voltage rails such as 3.3V. Confirm that the 4-SMD no-lead footprint matches your PCB layout constraints. Ensure compatibility with LVCMOS logic levels for signal integrity. Check availability status as marketplace products may have limited stock or specific shipping terms from the supplier Mercury Electronic Ind. Co., Ltd.

Selection Notes

Select this component when a stable 13.0625 MHz reference is required in space-constrained designs. The choice depends on the need for low-power standby functionality and standard LVCMOS compatibility. Consider the 2.5x2.0mm package size relative to available board real estate. Validate thermal performance and supply voltage tolerance against the target application environment before finalizing the bill of materials.

Part Context

This part belongs to the Mercury Electronic Ind. Co., Ltd. family of quartz crystal oscillators. The company specializes in frequency control products including crystals, filters, and oscillators. The 18QHTF series typically denotes standard XO units designed for general electronic applications. Mercury Electronics has been manufacturing these components since 1973, establishing them as a supplier in the Taiwan frequency-control market.

Replacement Considerations

Direct substitutes include other 13.0625 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pinout compatibility and electrical specifications such as load capacitance and drive strength. Alternative parts must support the same supply voltage range and physical footprint to ensure seamless integration without PCB redesign.
