18QHTF21-60.625-PD

Overview

The 18QHTF21-60.625-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 60.625 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down capabilities
• Provides LVCMOS output signal compatibility

Applications

• General clock generation for digital circuits
• Embedded systems requiring low-power oscillators
• Portable electronic devices

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 60.625 MHz reference is required with minimal power consumption. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the small 2.0x1.6mm form factor for space-constrained designs. Verify that the standby feature meets your system's power management strategy.

Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltages. The '18' prefix indicates the 1.8V supply variant. The 'PD' suffix denotes the inclusion of power-down functionality, distinguishing it from continuous-operation models within the same physical package family.

Replacement Considerations

Direct substitutes must match the 60.625 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-referencing other manufacturers requires verifying pinout compatibility and electrical specifications. Ensure any alternative part supports the standby function if required by the design.
