18QHTF21-106.600-OE

Overview

The 18QHTF21-106.600-OE is a 106.6 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a supply voltage of 1.8V and utilizes LVCMOS output logic. The device features an active low enable/disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for high-frequency timing applications requiring precise clock signals.

Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Active low enable/disable functionality for power efficiency
• Compact 4-SMD no-lead surface mount package

Applications

• High-speed data communication interfaces
• Embedded system clock generation
• Consumer electronics timing circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable/disable pin logic levels are compatible with your microcontroller or driver outputs to prevent unintended state changes during operation.

Selection Notes

Select this component when a 106.6 MHz clock signal is required in a space-constrained environment. The 1.8V operating voltage makes it suitable for modern low-power portable devices. Consider the LVCMOS output swing if interfacing with 3.3V logic domains, as level shifting may be necessary. The small footprint allows for dense PCB layouts.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6mm package. The 'OE' suffix typically denotes the presence of an output enable pin, distinguishing it from continuous-output variants. Mercury Electronics specializes in quartz crystal components with extensive industry experience.

Replacement Considerations

Direct replacements must match the 106.6 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, specifically the enable pin configuration. Cross-reference with other manufacturers offering similar low-profile oscillators, ensuring electrical parameters such as phase noise and jitter meet original specifications.
