18QHTF21-106.600-PD

Overview

The 18QHTF21-106.600-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 106.6 MHz and utilizes LVCMOS output logic levels. The device is designed for low voltage applications, specifically requiring a 1.8V supply voltage. It features a power-down function accessible via a standby control pin, allowing for reduced power consumption when not in use. The component is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• Supports LVCMOS output interface for digital signal compatibility
• Includes standby mode for power-down functionality
• Compact 4-SMD no-lead surface mount package design

Applications

• Digital communication systems requiring precise clock signals
• Data acquisition equipment needing stable timing references
• Embedded systems utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's current documentation to ensure compatibility with design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check for any updated quality certifications or RoHS compliance status directly from Mercury Electronics before finalizing procurement decisions.

Selection Notes

Select this component when a 106.6 MHz clock source is required within a low-voltage 1.8V environment. Ensure the application can accommodate the small 2.0x1.6 mm footprint. Consider the LVCMOS output swing limits relative to downstream logic inputs. Evaluate the necessity of the power-down feature for meeting specific energy efficiency targets in portable or battery-operated designs.
