18QHTF21-85.207-PD

Overview

The 18QHTF21-85.207-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 85.207 MHz and utilizes an LVCMOS output signal format. The device is designed for a supply voltage of 1.8V and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package suitable for surface mount applications.

Feature Summary

• Supports low voltage operation with 1.8V supply requirement
• Includes standby capability for power management
• Delivers standard LVCMOS output signals

Applications

• General purpose clock generation
• Embedded system timing
• Consumer electronics

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V operating voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Selection Notes

Select this component when a precise 85.207 MHz clock source is required for digital circuits. Consider the 1.8V supply constraint and LVCMOS compatibility with downstream logic. Evaluate the need for standby functionality to manage power consumption during idle periods. Compare package size and thermal characteristics against alternative oscillators if space or heat dissipation is a critical design factor.
