18QHTF21-60.5375-PD

Overview

The 18QHTF21-60.5375-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 60.5375 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, no lead package, designed for surface-mount applications.

Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode capability
• Provides LVCMOS signal output

Applications

• General clock generation in electronic circuits
• Data communication interface timing
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Check for any specific manufacturing date codes or lot traceability needs required by your quality standards.

Selection Notes

Select this component when a precise 60.5375 MHz clock source is required for LVCMOS-compatible digital logic. Consider the 1.8V operating voltage to ensure compatibility with low-power microcontrollers or FPGAs. The integrated power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Evaluate thermal performance if the device will operate near its maximum temperature limits.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small SMD form factor. The series is designed for modern electronics requiring stable clock signals in space-constrained environments. Mercury Electronics has established itself as a manufacturer of quartz crystals and oscillators since 1973.

Replacement Considerations

Direct substitutes must match the 60.5375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as jitter and phase noise if applicable. Cross-reference with other manufacturers offering similar surface-mount oscillators with identical footprint and voltage ratings.
