7V-14.31818MAAV-T

Crystals Overview

The 7V-14.31818MAAV-T is a surface-mount crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a nominal frequency of 14.31818 MHz with a load capacitance of 8 pF and a frequency tolerance of ±30 ppm. The component features an AT-cut resonator housed in a compact 3.2 mm x 2.5 mm SMD package. It supports a standard operating temperature range from -20°C to +70°C and utilizes a 4-SMD, no-lead footprint suitable for automated assembly processes.

Crystals Feature Summary

• AT-cut resonator technology ensures stable oscillation without requiring harmonic suppression networks.
• Compact 3.2 mm x 2.5 mm surface-mount package reduces board space requirements compared to traditional formats.
• Glass-sealed construction provides environmental protection and long-term frequency stability.

Crystals Applications

• Reference clock source for USB hubs
• Clock generation for audio codecs
• PCIe interface timing circuits

Crystals Procurement Notes

Verify the specific ordering suffix against official TXC documentation to confirm exact electrical parameters and packaging configurations. Ensure compatibility with the target circuit's load capacitance requirements, as variations exist within the product family. Confirm RoHS compliance status and moisture sensitivity level prior to procurement to align with manufacturing standards.

Crystals Selection Notes

Select this component when a precise 14.31818 MHz reference is required for legacy or compatible digital interfaces. Evaluate the 8 pF load capacitance requirement against the host oscillator circuit design to ensure accurate frequency tuning. Consider the -20°C to +70°C operating range suitability for the intended environmental conditions.

Crystals Part Context

This part belongs to the 7V series of crystals from TXC Corporation, which are widely used in consumer electronics and industrial control systems. The 14.31818 MHz frequency is a standard derived from the original PC clock speed, making it a common choice for interfacing with older peripheral standards and audio equipment that rely on this specific harmonic.

Crystals Replacement Considerations

Cross-reference with other 3225 package crystals offering identical 14.31818 MHz frequency, 8 pF load capacitance, and ±30 ppm tolerance. Verify pinout compatibility and physical dimensions before substitution to ensure seamless integration into existing PCB layouts.
