591PB-ADG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 591PB-ADG is a programmable crystal oscillator (XO) from the Si591 series, designed for general-purpose clock applications. It operates at a nominal voltage of 3.3 V and delivers a CMOS output format with a frequency stability of ±25 ppm. The device supports frequencies within the 10 MHz to 810 MHz range and features an enable pin for power management. Packaged in a compact 7 mm x 5 mm surface-mount footprint, it functions reliably across an industrial temperature range of -40°C to +85°C, making it suitable for various digital systems requiring precise timing signals.

Programmable Oscillators Feature Summary

• Programmable frequency generation capability within the specified operational range
• CMOS output interface compatible with standard logic levels
• Integrated enable control for active and low-power states

Programmable Oscillators Applications

• General-purpose clock distribution in digital systems
• Data communication equipment requiring stable timing references
• Industrial control systems needing reliable oscillators

Programmable Oscillators Procurement Notes

Verify the specific programming parameters, including target frequency and load capacitance, directly with the manufacturer or authorized distributor before ordering. Confirm that the CMOS output voltage levels align with the receiving circuit's input requirements. Ensure the 3.3 V supply voltage matches the system design specifications. Check for any required configuration tools or software needed to program the device correctly upon receipt.

Programmable Oscillators Selection Notes

Select this component when a programmable solution is required rather than a fixed-frequency oscillator. Consider the CMOS output format if single-ended signaling is sufficient for the application. Evaluate the ±25 ppm stability against system jitter requirements. Compare the 7 mm x 5 mm package size against available board space constraints relative to other Si591 variants.

Programmable Oscillators Part Context

The 591PB-ADG belongs to the Si591 family of standard clock oscillators manufactured by Skyworks Solutions. This series offers flexible programming options for various frequency needs. Unlike fixed-frequency models such as the 591AD360M000DGR, the PB suffix indicates programmability. The device shares the same physical dimensions and basic electrical characteristics as other members of the Si591 line, ensuring mechanical compatibility across the family.

Programmable Oscillators Replacement Considerations

For non-programmable applications, consider fixed-frequency alternatives like the 591NB500M000DGR if the exact frequency requirement is known. Verify that replacement parts maintain the same CMOS output format and 3.3 V operating voltage. Ensure any substitute part meets the same ±25 ppm stability and temperature range specifications.
