18QHTF21-64.516-OE

Overview

The 18QHTF21-64.516-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 64.516 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Enable/disable control functionality for power efficiency
• Compact 4-SMD no-lead surface mount package design

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure the correct voltage and output configuration. Confirm that the 1.8V supply requirement aligns with the target system design before procurement. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper assembly and electrical connection.

Selection Notes

Select this component when a 64.516 MHz clock source with LVCMOS outputs is required. The 1.8V operating voltage makes it suitable for low-power digital systems. The enable/disable feature allows for dynamic power management. Verify that the 4-SMD package dimensions fit within the available board space constraints.
