18QHTF21-61.625-PD

Overview

The 18QHTF21-61.625-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 61.625 MHz and utilizes LVCMOS output logic. The device supports a 2.5V supply voltage and includes a standby (power down) function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports low-power standby mode
• Provides stable LVCMOS clock signals
• Compact surface-mount form factor

Applications

• General digital circuit timing
• Embedded system clocks
• Communication interface synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint. Ensure the 2.5V supply voltage matches your system's power rails to guarantee proper operation and longevity of the component.

Selection Notes

Select this model when a fixed 61.625 MHz frequency is required with LVCMOS compatibility. Consider the 2.5V operating voltage and standby feature for power-sensitive designs. Evaluate the 4-SMD package size against available board space constraints compared to other Mercury oscillator series.

Part Context

This part belongs to the QHTF21 series from Mercury Electronic Ind. Co., Ltd., a manufacturer specializing in quartz crystals and oscillators. The series typically offers standard XO options with various frequencies and supply voltages, catering to general-purpose electronic timing needs across consumer and industrial electronics markets.

Replacement Considerations

Direct substitutes must match the 61.625 MHz frequency, LVCMOS output, 2.5V supply, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other Mercury models or industry-standard equivalents ensuring identical electrical parameters and mechanical dimensions.
