512BBA000442AAG

Overview

The Skyworks Solutions Inc. 512BBA000442AAG is a standard clock oscillator from the Si512 series, designed for high-performance clock generation in demanding applications. It operates at a fixed frequency of 74.25 MHz or 148.5 MHz with a frequency stability of ±25 ppm. The device utilizes an LVDS output format and functions within a supply voltage range of 2.97 V to 3.63 V, typically powered at 3.3 V. Encased in a compact 7 mm x 5 mm surface-mount package, it supports an operating temperature range from -40°C to +85°C. The component features pin-configurable outputs and includes enable/disable functionality, drawing a maximum current of 43 mA during operation.

Feature Summary

• Pin-configurable LVDS output architecture allows flexible signal routing and interface compatibility.
• Low-voltage, no-lead design minimizes electromagnetic interference (EMI) for sensitive systems.
• Integrated enable/disable control provides power management capabilities through active and standby states.

Applications

• High-speed data communication interfaces requiring precise timing signals
• Telecommunications equipment utilizing differential clock distribution
• Industrial control systems needing stable frequency references across wide temperature ranges

Procurement Notes

Verify the specific frequency variant required, as the part number covers both 74.25 MHz and 148.5 MHz options. Confirm the output configuration matches the target circuit design before ordering. Ensure the supply voltage aligns with the specified 3.3 V nominal requirement. Check the latest datasheet for any updates regarding mechanical dimensions or thermal characteristics. Validate that the manufacturer's lead time meets project schedules.

Selection Notes

Select this component when low jitter and high stability are critical for system performance. The Si512 series offers robust EMI reduction compared to traditional packages. Consider the LVDS output format for noise immunity in long trace applications. Evaluate the power consumption against system constraints, noting the difference between active and disabled states. Ensure the 7x5 mm footprint fits within the available PCB area.

Part Context

This oscillator belongs to the Si512 family of pin-configurable crystal oscillators. These devices are engineered to replace multiple discrete components by integrating the resonator and driver into a single surface-mount unit. The series is widely used in networking and storage applications where signal integrity is paramount.

Replacement Considerations

The 512BBA000442AAGR is listed as a parameter-equivalent substitute. Verify that the reel packaging does not impact the assembly process. Ensure the replacement maintains the same frequency and output format specifications.
