18QHTF21-103.000-PD

Overview

The 18QHTF21-103.000-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 103.0 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down function via standby mode. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. The component supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode capability for power-down functionality
• Utilizes a small form factor 4-SMD no-lead package

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 103.0 MHz
• Embedded devices utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure the correct pinout and electrical specifications are matched. Confirm that the required operating temperature range aligns with the -40°C to 85°C specification provided in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a precise 103.0 MHz timing source is required within a constrained board space. The 1.8V supply requirement dictates compatibility with low-voltage logic families. Ensure the design accommodates the 2.0x1.6mm footprint and considers the thermal environment relative to the specified industrial temperature limits.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized physical package. The 'PD' suffix indicates the inclusion of power-down control capabilities, distinguishing it from standard continuous-operation variants within the same family.

Replacement Considerations

Direct replacements must match the 103.0 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package dimensions. Verify that any substitute component supports the same standby power-down functionality and meets the -40°C to 85°C operating temperature range requirements.
