571BAA000112DG

Oscillators Overview

The Skyworks Solutions Inc. 571BAA000112DG is a programmable VCXO from the Si571 series, housed in an 8-SMD (7 mm x 5 mm) package. It operates on a supply voltage of 3.3 V (range 2.97 V to 3.63 V) with a maximum current draw of 99 mA. The device features LVDS output format and supports frequencies from 10 MHz to 1.4175 GHz. It includes a programmable enable/disable function and offers frequency stability of ±20 ppm with an absolute pull range of ±12 ppm. Operating temperatures range from -40°C to +85°C.

Oscillators Feature Summary

• I2C programmable control for flexible frequency configuration
• Integrated enable/disable pin for power management
• LVDS differential output interface for signal integrity

Oscillators Applications

• High-speed serial communication interfaces
• Clock distribution networks
• Data converter clocking systems

Oscillators Procurement Notes

Verify the specific output format and frequency parameters against your system requirements before ordering. Confirm that the LVDS interface is compatible with your receiving logic. Ensure the operating temperature range meets your environmental conditions. Check for any recent product change notifications or lifecycle status updates from the manufacturer to ensure long-term availability.

Oscillators Selection Notes

Select this component when a low-jitter, I2C-programmable VCXO with LVDS outputs is required. Compare it against the Si570 series if frequency tuning range is less critical than cost. Consider the Si571AJA variant if LVPECL outputs are preferred over LVDS. Verify that the 7x5 mm footprint fits within your PCB layout constraints.

Oscillators Part Context

This part belongs to the Si571 family of wide-range programmable oscillators. It shares the same physical package and core architecture as other Si571 variants but differs in output format and specific factory-set parameters. It is designed to replace fixed-frequency crystals and resonators in high-performance digital systems requiring precise clock generation.
