512ACA000132AAG

Overview

The Skyworks 512ACA000132AAG is a standard crystal oscillator (XO) from the Si512 series, designed for general-purpose timing applications. It operates at a supply voltage of 3.3V and delivers an LVPECL output format. The device supports dual frequency outputs of 128.788 MHz and 156.25 MHz with a frequency stability of ±20 ppm. It features a 6-SMD, no-lead package measuring 7 mm x 5 mm x 1.80 mm. The component functions within a temperature range of -40°C to +85°C and draws a maximum current of 43 mA during operation.

Feature Summary

• Supports dual frequency selection between 128.788 MHz and 156.25 MHz
• Provides LVPECL output format for high-speed digital interfaces
• Features pin-configurable enable/disable functionality
• Operates on a single 3.3V power supply

Applications

• High-speed data communication systems
• Network infrastructure equipment
• Server and storage subsystems
• Test and measurement instruments

Procurement Notes

Verify the specific output frequency configuration required for the design, as this part supports dual frequencies. Confirm that the LVPECL output level matches the receiving component's input requirements. Ensure the PCB footprint accommodates the 7x5mm SMD package dimensions and thermal relief needs for reliable soldering.

Selection Notes

Select this component when dual-frequency flexibility is needed within a compact form factor. The LVPECL output is suitable for differential signaling applications requiring low jitter. Consider the 3.3V supply constraint and ensure the system power budget accounts for the 43 mA maximum current draw. Verify environmental compliance if operating in extreme temperatures beyond the specified range.

Part Context

This oscillator belongs to the Si512 family of pin-configurable clock generators. These devices offer design flexibility by allowing frequency and output format selection through external pin connections. The family targets applications requiring precise timing with minimal board space, integrating multiple functions into a single surface-mount package.

Replacement Considerations

The 512ACA000132AAGR is a parameter-equivalent alternative available in reel packaging. Both parts share identical electrical specifications and package dimensions. Verify that the reel packaging option meets production handling requirements without altering functional performance.
