8Z-38.400MAAV-T

Crystals Overview

The TXC Corporation 8Z-38.400MAAV-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 38.4 MHz. It features a frequency stability and tolerance of ±30 ppm, with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ohms. The component utilizes ceramic construction and is housed in a compact 4-SMD, no-lead package measuring 3.20 mm in length, 2.50 mm in width, and up to 0.90 mm in height. It supports base harmonic operation and functions within a temperature range of -40°C to +85°C.

Crystals Feature Summary

• Compact 4-SMD no-lead ceramic package for space-constrained designs
• High frequency stability of ±30 ppm for precise timing applications
• Low equivalent series resistance of 60 Ohms for efficient circuit integration

Crystals Applications

• Microcontroller clock sources
• Communication module timing circuits
• Embedded system synchronization

Crystals Procurement Notes

Verify the specific suffix 'AAV' against the manufacturer's official part number guide to ensure correct load capacitance and tolerance specifications. Confirm that the 4-SMD footprint dimensions align with the PCB land pattern requirements. Check RoHS compliance status and moisture sensitivity level ratings prior to assembly planning.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency with ±30 ppm stability is required in a small form factor. Ensure the target circuit design accommodates an 8 pF load capacitance and can handle the specified ESR. Verify that the operating temperature range of -40°C to +85°C meets the environmental constraints of the final application.

Crystals Part Context

This part belongs to the TXC 8Z series of ceramic crystals, designed for general-purpose timing applications requiring low cost and small size. It serves as a passive frequency control element, distinct from active oscillators by requiring external driver circuitry to generate a square wave output signal.
