591WB-DDG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 591WB-DDG is a programmable standard crystal oscillator (XO) from the Si591 series, designed for general-purpose clocking applications. It operates within a frequency range of 10 MHz to 810 MHz and utilizes a crystal base resonator. The component features an enable/disable function and is housed in a compact 6-SMD, no-lead package measuring 7.00 mm x 5.00 mm with a maximum height of 1.80 mm. It supports a supply voltage of 2.5 V and functions reliably across an operating temperature range of -40°C to +85°C.

Programmable Oscillators Procurement Notes

This part is programmed by Digi-Key upon order placement. Customers must specify the required frequency in the Web Order Notes during purchase. Verify that the requested frequency falls within the supported 10 MHz to 810 MHz range before submission to ensure correct configuration and avoid programming errors.

Programmable Oscillators Selection Notes

Select this model when a specific frequency outside standard fixed values is required within the 10-810 MHz spectrum. Ensure the system design accommodates the 2.5 V supply requirement and the 6-SMD footprint dimensions. Confirm that the ±20 ppm stability meets the application's jitter and phase noise requirements.

Programmable Oscillators Part Context

The 591WB-DDG belongs to the Si591 family of single-frequency general-purpose oscillators. This series provides flexible clock solutions with various output formats and stability options. The WB suffix indicates a programmable variant, distinguishing it from fixed-frequency models in the same package family.

Programmable Oscillators Replacement Considerations

For equivalent performance, consider other Si591 series programmable oscillators or fixed-frequency variants if the exact frequency is not needed. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
