18QHTF21-102.336-PD

Overview

The 18QHTF21-102.336-PD is a 102.336 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It utilizes LVCMOS output logic and operates at a supply voltage of 1.8V. The device features a power-down function for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• LVCMOS output logic interface
• Integrated power-down capability
• Compact surface-mount form factor

Applications

• General clock signal generation
• Digital system timing references
• Embedded controller circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 2.0x1.6mm footprint matches the PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliability during assembly processes.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 102.336 MHz reference frequency. The small 2.0x1.6mm package makes it suitable for space-constrained designs. Consider the LVCMOS output compatibility with downstream digital logic levels. Evaluate the need for power-down functionality if energy efficiency during idle states is a critical design parameter.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of standard crystal oscillators. The series typically offers various frequencies and supply voltages within a consistent small outline package family. Mercury Electronics specializes in quartz-based frequency control products, including crystals, TCXOs, and VCTCXOs, serving global electronics manufacturing needs.

Replacement Considerations

Direct substitutes include other 102.336 MHz LVCMOS oscillators in 2.0x1.6mm packages from different manufacturers, provided electrical parameters match. Verify pinout compatibility and operating voltage ranges. Cross-reference with similar Mercury parts like the 18QHTF32 series if package size differences are acceptable.
