8Y-38.400MDIV-T

Crystals Overview

The 8Y-38.400MDIV-T is a surface-mount MHz quartz crystal manufactured by TXC Corporation. It operates at a nominal frequency of 38.4 MHz with a high frequency stability of ±20 ppm. The component utilizes an 8 pF load capacitance and exhibits an equivalent series resistance (ESR) of 80 Ohms. Designed for base resonance mode, it is housed in a compact 4-SMD, no-lead package measuring 2.0 mm by 1.6 mm.

Crystals Feature Summary

• High frequency stability of ±20 ppm ensures precise timing accuracy.
• Ultra-miniature 2.0x1.6 mm seam seal package design.
• Optimized for low series resistance applications.

Crystals Applications

• Precision clock generation in embedded systems
• Timing references for microcontrollers
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific package dimensions and ESR requirements against the target circuit design before procurement. Confirm that the ±20 ppm stability meets the system's jitter and phase noise specifications. Ensure the 8 pF load capacitance matches the oscillator circuit's external capacitors to maintain accurate frequency output.

Crystals Selection Notes

Select this component when tight frequency tolerance is required within a minimal footprint. The 80 Ohm ESR suits circuits with moderate drive levels. Compare against standard ±30 ppm variants if cost reduction is prioritized over precision. Verify compatibility with the host device's input capacitance.

Crystals Part Context

This part belongs to TXC's 8Y Series of high-accuracy MHz crystals. The series is characterized by extremely low aging and high Q factors. It serves as a specialized alternative to standard crystals where long-term stability and precise frequency control are critical for system performance.
