18QHTF21-60.860-PD

Overview

The 18QHTF21-60.860-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 60.86 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm. The component supports surface-mount technology for automated assembly processes.

Feature Summary

• Supports low-voltage operation at 1.8V with integrated power-down capability
• Delivers stable LVCMOS signal output for digital circuit interfacing
• Utilizes a miniature 4-SMD no-lead package for space-constrained designs

Applications

• Clock generation for high-speed digital processors
• Timing reference for communication interface modules
• Synchronization sources for embedded system controllers

Procurement Notes

Verify the specific ordering suffix matches the required frequency tolerance and load capacitance specifications. Confirm that the package variant aligns with the designated footprint on the printed circuit board. Ensure the supply voltage requirements are compatible with the target system's power rail before finalizing the procurement order.

Selection Notes

Select this component when a precise 60.86 MHz timing source is required for low-power applications. Consider the 1.8V operating voltage constraint and the need for a power-down feature during idle states. Evaluate the physical size constraints against the 2.0x1.6 mm package dimensions to ensure compatibility with the design layout.
