18QHTF21-88.500-PD

Overview

The 18QHTF21-88.500-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 88.5 MHz and utilizes an LVCMOS output interface. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features a Standby mode for power management and is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output signaling for digital logic compatibility
• Includes Standby functionality to reduce power consumption during idle periods
• Utilizes a surface-mount 4-pin no-lead package for automated assembly

Applications

• Battery-powered portable electronic devices
• General-purpose digital logic clock generation
• Communication equipment requiring precise timing signals

Procurement Notes

Verify the specific orderable part number against the manufacturer's official documentation to ensure accuracy. Confirm that the required operating temperature range and load capacitance specifications align with the target circuit design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a low-profile 2.0x1.6 mm footprint is required for space-constrained designs. Ensure the system architecture supports 1.8V logic levels and can accommodate the specified standby control signals. Validate that the 88.5 MHz frequency matches the exact timing needs of the application without requiring external dividers or multipliers.

Part Context

This model belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a supplier specializing in quartz crystals and oscillators. The series typically offers various frequency options within a standardized small outline package format, catering to modern electronics requiring miniaturized timing solutions.

Replacement Considerations

Direct substitutes must match the 88.5 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm SMD package. Verify pinout compatibility and electrical characteristics with alternative manufacturers offering similar surface-mount crystal oscillators.
