18QHTF21-69.330-PD

Overview

The 18QHTF21-69.330-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 69.33 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down standby function for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for applications requiring precise timing signals in space-constrained electronic systems.

Feature Summary

• LVCMOS output interface for digital circuit compatibility
• Integrated power-down standby mode to reduce consumption
• Compact surface-mount package suitable for high-density PCB layouts

Applications

• Consumer electronics timing circuits
• Communication equipment clock sources
• Industrial control system synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this oscillator when a 69.33 MHz reference signal is needed with low power consumption capabilities. The LVCMOS output is suitable for direct interfacing with digital logic without additional buffering. Consider the 1.8V operating voltage if your system utilizes lower voltage domains. The small form factor makes it ideal for portable devices where board space is limited.
