X10CB1-24.576MHZ-T

Crystals Overview

The X10CB1-24.576MHZ-T is a 24.576 MHz fundamental mode AT-cut quartz crystal resonator from MMD's X Series. It features a compact 2.5mm x 2.0mm surface-mount package with four solder pads and no leads. The component operates within a frequency tolerance of ±15 ppm at room temperature, utilizing a standard load capacitance of 10 pF. Its equivalent series resistance (ESR) is specified at a maximum of 80 ohms for the 20-29.999 MHz range. The device supports an operating temperature range starting from -20°C to +70°C or +85°C depending on specific configuration, ensuring stability for digital clock applications.

Crystals Feature Summary

• Ultra-compact 2.5mm x 2.0mm footprint designed for space-constrained PCB layouts
• Fundamental AT-cut quartz construction ensures high frequency stability and low phase noise
• Standard 10pF load capacitance simplifies circuit design without requiring external compensation components

Crystals Applications

• Microcontroller unit (MCU) clock sources in wearable devices
• Bluetooth Low Energy (BLE) module timing references
• Low-power IoT sensor nodes
• Smartwatch and fitness tracker mainboards

Crystals Procurement Notes

Verify the specific suffix and tape/reel specifications against the official datasheet before ordering. Confirm that the required operating temperature range matches the application environment, as variations exist within the X Series. Ensure the ESR limits align with the oscillator circuit design to guarantee reliable startup conditions under all thermal conditions.

Crystals Selection Notes

Select this component when board real estate is limited, as the 2520 package offers significant area reduction compared to standard 3225 crystals. The 24.576 MHz frequency is optimal for generating precise baud rates in UART and SPI interfaces. Consider the 80 ohm ESR limit when designing the oscillator feedback network to ensure adequate drive level margins.

Crystals Part Context

This part belongs to MMD's X Series, a line of miniature quartz crystals engineered for modern consumer electronics. The series prioritizes miniaturization while maintaining industrial-grade reliability. The 24.576 MHz variant is a common choice for communication protocols requiring exact timing divisions.

Crystals Replacement Considerations

Direct substitutes include other 2520 package crystals with identical 24.576 MHz frequency, 10pF load capacitance, and ESR below 80 ohms. Verify pin compatibility and mounting pad dimensions to ensure mechanical interchangeability without redesigning the PCB footprint.
