591SB-CDG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 591SB-CDG is a programmable crystal oscillator (XO) from the Si591 series, supporting frequency ranges from 10 MHz to 810 MHz. It features LVDS output format and operates on a 2.5 V supply voltage with a typical current consumption of 110 mA. The device offers a frequency stability of ±25 ppm and functions within an operating temperature range of -40°C to +85°C. Housed in a compact 6-SMD, no-lead package measuring 7 mm x 5 mm x 1.65 mm, it includes enable/disable functionality for power management.

Programmable Oscillators Feature Summary

• Supports programmable frequencies across a wide range from 10 MHz to 810 MHz
• Delivers differential LVDS output signals for high-speed applications
• Integrates enable/disable control pin for active power management

Programmable Oscillators Applications

• High-speed data communication interfaces requiring precise clocking
• Telecommunications equipment and base stations
• Network infrastructure and switching systems
• Test and measurement instrumentation

Programmable Oscillators Procurement Notes

Verify the specific target frequency during ordering as this is a programmable component. Confirm that the required LVDS output format aligns with the receiving circuit's input specifications. Ensure the 2.5 V supply voltage requirement is compatible with the system design. Check the ±25 ppm stability against application timing constraints. Validate the 6-SMD package dimensions for PCB layout compatibility.

Programmable Oscillators Selection Notes

Select this model when a flexible frequency solution within the 10-810 MHz range is needed without custom mask programming. The LVDS output is suitable for noise-sensitive high-speed digital environments. Consider the 2.5 V operation if lower voltage than standard 3.3V oscillators is preferred. The programmable nature allows for inventory reduction by using one part number for multiple frequency requirements.
