18QHTF21-87.0655-PD

Overview

The 18QHTF21-87.0655-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 87.0655 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down function for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy management
• Utilizes LVCMOS output interface

Applications

• General clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure that the 1.8V supply rail stability meets the oscillator's operational needs. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions to avoid assembly issues during manufacturing.

Selection Notes

Select this component when a precise 87.0655 MHz reference is required in space-constrained designs. The choice is driven by the need for low-power consumption via the standby feature and compatibility with 1.8V logic families. Consider the small form factor as a primary advantage for dense board layouts.

Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series is characterized by its small footprint and low power consumption options. It serves as a fundamental timing element in modern electronic devices requiring stable clock signals without the bulk of through-hole components.

Replacement Considerations

Direct substitutes must match the 87.0655 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if available in competitor datasheets.
