18QHTF21-10.5375-PD

Overview

The 18QHTF21-10.5375-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 10.5375 MHz. It utilizes LVCMOS output logic and functions with a 1.8V supply voltage. The device features a standby mode for power down capabilities. 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 standby functionality to reduce power consumption during idle states
• Designed as a standard XO (Crystal Oscillator) unit

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a precise 10.5375 MHz clock source is required for low-voltage digital applications. Consider the 1.8V operating voltage and LVCMOS output levels to ensure compatibility with downstream logic gates. Evaluate the small 2.0x1.6 mm package size against available board space. Verify that the standard oscillator type meets the phase noise and stability needs of your application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and frequency control products. The manufacturer has been producing these components since 1973. This series typically includes various frequencies within a standardized SMD form factor, catering to diverse electronic timing needs across consumer and industrial electronics markets.

Replacement Considerations

Direct substitutes include other 10.5375 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Cross-reference pinouts and electrical characteristics carefully. Alternative models from different manufacturers may require verification of output drive strength and loading capacitance.
