ATS143B

Crystals Overview

The ATS143B is a fundamental mode crystal resonator manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 14.31818 MHz with a frequency tolerance of ±30 ppm and a frequency stability of 50 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 40 Ohms maximum. It utilizes the HC-49/US package style, designed for through-hole mounting. This crystal is engineered for use in timing circuits requiring precise clock generation.

Crystals Feature Summary

• Fundamental mode operation for stable frequency generation
• Through-hole mounting configuration via HC-49/US package
• Designed for precision timing and clock circuit applications

Crystals Applications

• Clock generation in computer systems
• Timing circuits in smartphones
• Digital device synchronization

Crystals Procurement Notes

Verify the specific suffix designation when ordering, as variants such as ATS143B-E exist within the same product family. Confirm that the required package type matches the target PCB layout, as this model specifies through-hole installation. Ensure the load capacitance requirements of the host oscillator circuit align with the 18 pF specification to maintain accurate frequency performance.

Crystals Selection Notes

Select this component when a fundamental mode crystal with HC-49/US packaging is required for through-hole assembly. It is suitable for designs needing a 14.31818 MHz reference with moderate stability requirements. Consider surface-mount alternatives if space constraints or automated SMT assembly processes are primary design drivers.

Crystals Part Context

This part belongs to the standard crystal resonator category from CTS-Frequency Controls. It serves as a passive frequency-determining element in electronic circuits. Unlike active oscillators, it requires an external oscillator circuit to function. It is distinct from the CA32 series which offers integrated output signals in surface-mount packages.

Crystals Replacement Considerations

The ATS143B-E is a documented variant within the same series. Verify compatibility before substitution.
