AV-14.31818MAHV-T

Crystals Overview

The AV-14.31818MAHV-T is a surface-mount MHz crystal manufactured by TXC Corporation, designed for automotive applications with AEC-Q200 certification. It operates at a fundamental frequency of 14.31818 MHz with a load capacitance of 8 pF and an equivalent series resistance of 120 Ohms. The component offers a frequency tolerance of ±30 ppm and stability of ±30 ppm across a temperature range of -40°C to +85°C. Housed in a compact 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm, it supports reflow soldering processes suitable for high-volume production environments.

Crystals Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Fundamental mode operation for precise timing
• Compact SMD footprint for space-constrained designs

Crystals Applications

• Automotive infotainment systems
• Engine control units (ECU)
• Telematics modules

Crystals Procurement Notes

Verify the specific suffix HV against the official TXC datasheet to confirm the exact temperature range and packaging configuration. Ensure that the AEC-Q200 certification requirements align with the target automotive application's quality standards. Cross-reference the 4-SMD package dimensions with PCB layout guidelines to prevent assembly errors during manufacturing.

Crystals Selection Notes

Select this component when automotive-grade reliability is required alongside a standard 14.31818 MHz reference frequency. The 8 pF load capacitance must match the oscillator circuit design specifications. Consider the 120 Ohm ESR value for impedance matching within the host system's clock generation architecture.

Crystals Part Context

This part belongs to the AV series of automotive crystals from TXC Corporation. It is distinct from MEMS oscillators like the TA series or CMOS XO devices such as the 7W series. The AV series focuses on passive crystal elements certified for harsh automotive environments rather than active output drivers.
