18QHTF21-57.735-OE

Overview

The 18QHTF21-57.735-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 57.735 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control functionality
• Compact surface-mount package design

Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application environment before procurement. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the PCB footprint matches the 4-SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a precise 57.735 MHz clock source is required for low-voltage digital systems. The LVCMOS output ensures compatibility with standard logic families. Consider the enable/disable feature if power management or clock gating is necessary within the design. The small form factor makes it suitable for space-constrained portable or industrial electronics.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, which specializes in quartz-based frequency control products. The series offers various frequencies and voltage options.
