18QHTF21-86.105-PD

Overview

The 18QHTF21-86.105-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 86.105 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby power-down mode to reduce energy consumption during inactive periods. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm by 1.6mm. This component serves as a precise clock source for digital circuits requiring stable frequency generation.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby power-down functionality
• Utilizes LVCMOS output interface

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific ordering suffix and frequency tolerance requirements against the official datasheet before procurement. Ensure that the 1.8V supply voltage aligns with the target circuit design. Confirm the 4-SMD package footprint matches the PCB layout specifications. Cross-reference the part number with the manufacturer's latest documentation to ensure availability and compliance with current manufacturing standards.

Selection Notes

Select this oscillator when a precise 86.105 MHz reference is required for LVCMOS-compatible logic families. Consider the 1.8V operating voltage constraint and the need for power-down capabilities. Evaluate the small 2.0x1.6mm form factor against available board space. Compare performance characteristics such as phase noise and stability if specified in the full technical documentation.

Part Context

This model belongs to the Mercury Electronics SMD oscillator series, which includes various frequencies and package types. The 18QHTF21 prefix indicates a specific family of surface-mount oscillators. Similar models in this range include variants with different frequencies such as 18.1059 MHz or 51.2 MHz, sharing the same physical package and electrical interface characteristics.

Replacement Considerations

Direct substitutes must match the 86.105 MHz frequency, LVCMOS output, and 1.8V supply voltage. Verify pin compatibility and package dimensions (2.0x1.6mm) for mechanical fit. Consult the manufacturer's cross-reference list for approved alternative part numbers.
