18QHTF21-13.600064-PD

Overview

The 18QHTF21-13.600064-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.600064 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby function for power down control. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output interface
• Standby power down capability
• Compact 4-SMD no lead package

Applications

• Digital signal processing systems
• Communication equipment timing
• Embedded microcontroller clocks

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific RoHS or environmental compliance certifications required for your region.

Selection Notes

Select this component when a stable 13.600064 MHz clock source is needed with low voltage operation. The LVCMOS output is suitable for direct interfacing with digital logic families. Consider the standby feature if power management during idle periods is critical. Verify temperature range specifications against your operating environment.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'PD' suffix typically indicates the inclusion of a power-down pin or functionality. This specific model provides a non-standard frequency often used in specialized communication protocols.

Replacement Considerations

Direct replacements must match the 13.600064 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter. Consult manufacturer cross-reference lists for equivalent parts from other suppliers.
