18QHTF21-86.893-PD

Overview

The 18QHTF21-86.893-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 86.893 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down (PD) control function for standby management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes power-down functionality for energy-efficient standby modes
• Utilizes a small form factor surface-mount package

Applications

• Embedded systems requiring precise clock signals
• Communication modules needing stable frequency references
• Portable electronic devices with space constraints

Procurement Notes

Verify the specific suffix PD indicates power-down capability when sourcing replacements. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 2.0x1.6mm footprint aligns with the PCB layout specifications to avoid assembly issues during procurement.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 86.893 MHz frequency. The LVCMOS output is suitable for standard digital logic families. Consider the power-down feature if system-level power management is a priority for the application design.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has a long history in Taiwan's crystal industry. This series typically offers various frequencies and package options for diverse electronic applications.

Replacement Considerations

Direct substitutes must match the 86.893 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm SMD package. Verify that alternative components also support the power-down control function to maintain equivalent operational capabilities.
