18QHTF21-86.630-PD

Overview

The 18QHTF21-86.630-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 86.63 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, no-lead package designed for surface-mount assembly.

Feature Summary

• LVCMOS output interface
• Integrated standby control
• Surface-mount SMD package

Applications

• General clock signal generation
• Digital system timing references
• Embedded electronics

Procurement Notes

Verify the specific frequency tolerance and stability specifications against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target circuit design requirements. Ensure the 4-SMD no-lead package dimensions are compatible with the PCB footprint to guarantee proper mechanical fit and solder joint integrity during assembly.

Selection Notes

Select this component when a precise 86.63 MHz reference is required with low-power standby capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the operating temperature range and stability requirements to ensure reliable performance within the intended application environment.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, all sharing a common small-form-factor SMD package. These oscillators are designed for applications requiring stable clock signals in space-constrained electronic devices.

Replacement Considerations

Direct substitutes must match the 86.63 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical parameters such as load current and duty cycle before substitution.
