8Y-24.000METC-T

Crystals Overview

The 8Y-24.000METC-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation, designed for precise clock signal generation in electronic circuits. It operates at a fundamental frequency of 24 MHz with a load capacitance of 12 pF. The component exhibits a frequency tolerance and stability of ±10 ppm at 25°C, maintaining this accuracy across an operating temperature range of -30°C to +85°C. It features a compact 2.0 mm x 1.6 mm seam seal ceramic package with a height of 0.5 mm, utilizing four solder pads for SMD/SMT mounting. The equivalent series resistance (ESR) is specified at 100 Ohms, with a maximum drive level of 50 uW.

Crystals Feature Summary

• Seam-sealed ceramic construction provides environmental protection and mechanical stability for the quartz resonator element.
• Compact surface-mount footprint enables high-density PCB layout and automated assembly processes.
• Stable frequency performance maintained across extended industrial temperature ranges without external compensation.

Crystals Applications

• Clock signal generation for microprocessors and microcontrollers
• Timing references for communication interfaces such as USB and Ethernet
• Synchronization sources for digital logic circuits and memory modules

Crystals Procurement Notes

Verify the specific suffix METC against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the design-in process accounts for the 12 pF load capacitance requirements of the host circuit. Confirm that the operating temperature range meets the environmental specifications of the final application before procurement.

Crystals Selection Notes

Select this component when a 24 MHz reference is required in a space-constrained area with moderate stability needs. Compare the ±10 ppm stability against tighter requirements like ±5 ppm or ±20 ppm alternatives if cost or availability varies. Consider the 100 Ohm ESR value to ensure it matches the oscillator circuit's loading requirements for reliable startup.

Crystals Part Context

This part belongs to the 8Y series of seam-seal crystals from TXC Corporation, which are characterized by their small ceramic packages. It serves as a passive timing element distinct from active oscillators, requiring an external oscillator circuit to generate a square wave output. It is commonly used in consumer electronics and industrial control systems where size and cost efficiency are prioritized.

Crystals Replacement Considerations

Direct substitutes include the 8Q-24.000METE-T and QT161S-24.000MEEQ-T, though package dimensions differ. Verify electrical parameters such as load capacitance and ESR when cross-referencing with other 24 MHz crystals from different manufacturers to ensure circuit compatibility.
