18QHTF21-86.558-PD

Overview

The 18QHTF21-86.558-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 86.558 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 with dimensions of 2.0mm by 1.6mm. This component is designed for timing applications requiring precise frequency generation within low-voltage digital systems.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power reduction
• Compact surface-mount package design

Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this oscillator when a stable 86.558 MHz reference is needed in space-constrained designs. The LVCMOS output simplifies integration with standard logic families. Consider the power-down capability if battery life or thermal management is critical. Verify that the operating temperature range meets your environmental specifications.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix typically indicates the inclusion of a power-down control pin. These components are widely used in consumer electronics and industrial applications requiring reliable timing signals.

Replacement Considerations

Direct substitutes must match the 86.558 MHz frequency, 1.8V operation, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter. Consult manufacturer cross-reference lists for approved alternatives.
