18QHTF21-102.894-PD

Overview

The 18QHTF21-102.894-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 102.894 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Feature Summary

• Integrates LVCMOS output logic for digital signal compatibility
• Supports standby mode to reduce power consumption during idle periods
• Utilizes a leadless surface-mount package for space-efficient PCB integration

Applications

• Digital clock generation in communication systems
• Timing reference for high-speed data interfaces
• Clock source for embedded microprocessors

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails before procurement.

Selection Notes

Select this component when a precise 102.894 MHz timing reference is required within a low-voltage 1.8V environment. The choice depends on the necessity for LVCMOS outputs and the availability of a 2.0x1.6mm footprint on the printed circuit board layout.

Part Context

This model belongs to the Mercury Electronics XO series, designed for general-purpose timing applications. The product line emphasizes compact form factors and standard logic outputs, catering to modern electronic devices requiring reliable frequency control in minimal spaces.

Replacement Considerations

The 18QHTF22-102.894-PD serves as a potential substitute, offering the same frequency but utilizing a larger 2.5x2.0mm package. Ensure mechanical clearance allows for the dimension change before considering this alternative.
