591CB-BDG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 591CB-BDG is a programmable single-frequency crystal oscillator (XO) from the Si591 series, designed for high-performance clock generation. It features an LVDS output format and operates on a 2.5V supply voltage with enable/disable functionality. The device supports frequencies between 125MHz and 214.999MHz, offering a frequency stability of ±20ppm and overall stability of ±30ppm. Housed in a compact 6-SMD, no-lead package measuring 7.00mm x 5.00mm x 1.80mm, it functions within a temperature range of -40°C to +85°C, consuming a maximum current of 100mA.

Programmable Oscillators Feature Summary

• Programmable frequency generation within the 125MHz to 214.999MHz range
• LVDS differential output interface for signal integrity
• Enable/Disable control pin for power management
• Compact surface-mount packaging suitable for dense layouts

Programmable Oscillators Applications

• High-speed data communication interfaces
• Telecommunications equipment clocking
• Network infrastructure timing solutions
• Industrial control systems requiring precise frequency references

Programmable Oscillators Procurement Notes

Verify the specific target frequency requirement before ordering, as this component requires programming by Digi-Key or authorized distributors. Confirm that the 2.5V supply voltage aligns with your system design, as it differs from the common 3.3V standard found in other Si591 variants. Ensure the LVDS output compatibility matches your receiving circuitry. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Programmable Oscillators Selection Notes

Select the 591CB-BDG when a programmable solution is needed for frequencies above 125MHz with LVDS outputs. Compare against the 591BB series if a fixed frequency is acceptable, as those may offer different voltage options like 3.3V. Consider the 511 series if smaller footprints or lower frequencies are required. Verify that the ±20ppm stability meets your jitter and phase noise specifications for the intended application environment.

Programmable Oscillators Part Context

The 591CB-BDG belongs to the Si591 family of standard oscillators manufactured by Skyworks Solutions. This series provides flexible clocking options for various digital applications. Unlike fixed-frequency models, this variant allows for custom frequency programming, making it suitable for designs requiring specific non-standard clock rates within its operational range while maintaining industry-standard form factors.
