18QHTF21-8.600-PD

Overview

The 18QHTF21-8.600-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 8.6 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and an integrated standby or power-down mode to minimize energy consumption during idle periods. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm, suitable for space-constrained surface-mount designs.

Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Supports standby mode for effective power management
• Utilizes a compact 4-SMD no-lead surface-mount package

Applications

• Portable electronic devices requiring low power consumption
• Embedded systems utilizing LVCMOS logic levels
• Compact consumer electronics with limited board space

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. 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 specifications to guarantee proper soldering and mechanical stability.

Selection Notes

Select this component when a precise 8.6 MHz clock signal is required with minimal power usage. The LVCMOS output ensures compatibility with standard digital logic families. Consider the small form factor if board real estate is limited. Verify environmental operating temperature ranges to ensure reliability under your specific application conditions.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same physical footprint. The series provides standardized XO solutions with consistent electrical characteristics across different frequency options, allowing for design flexibility while maintaining uniform packaging and interface standards.

Replacement Considerations

Direct substitutes include other 8.6 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Ensure replacement parts match the 1.8V supply requirement and standby functionality. Verify pinout compatibility and thermal performance metrics to maintain system integrity without redesigning the host circuit.
