512BAA001112BAG

Overview

The Skyworks Si512BAA001112BAG is a pin-configurable standard crystal oscillator (XO) designed for general-purpose applications. It features dual frequency outputs of 50 MHz and 156.25 MHz with a frequency stability of 30 PPM. The device utilizes LVPECL output format and operates within a supply voltage range of 2.97 V to 3.63 V, typically at 3.3 V. It supports an enable/disable function via Pin 2 and draws a maximum current of 39 mA. The component is housed in a compact 3.2 mm x 2.5 mm surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific part number against official Skyworks documentation to confirm the LVPECL output configuration and dual-frequency specifications. Ensure that the procurement source provides valid RoHS compliance information. Confirm that the supplier can meet the standard lead time requirements and that the component is sourced from authorized channels to guarantee authenticity and performance reliability.

Selection Notes

Select this component when dual-frequency generation is required within a single package to reduce board space. The LVPECL output is suitable for noise-sensitive high-speed digital circuits. Consider the 30 PPM stability requirement and the 3.3 V supply constraint during system design. Verify that the 3.2 mm x 2.5 mm footprint aligns with the PCB layout constraints and thermal management requirements of the target application.

Part Context

This model belongs to the Skyworks Si512 series of pin-configurable crystal oscillators. The series offers various output formats and frequency options tailored for different interface standards. The 512BAA001112BAG specifically addresses applications needing both 50 MHz and 156.25 MHz signals with low jitter and stable performance in demanding environments.

Replacement Considerations

Direct substitutes must match the Si512 family, LVPECL output, and dual-frequency specification. Verify pin compatibility and electrical parameters before substitution.
