591BA-CDG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 591BA-CDG is a programmable single-frequency crystal oscillator (XO) from the Si591 series, designed for general-purpose clocking applications. It operates within a frequency range of 10 MHz to 525 MHz and delivers an LVDS output format. The device supports a supply voltage of 3.3 V with a typical current consumption of 100 mA. Frequency stability is specified at ±50 ppm. It features an enable/disable control function and utilizes a 6-SMD, no-lead package measuring 7 mm x 5 mm. The component is rated for operation between -40°C and +85°C.

Programmable Oscillators Feature Summary

• Programmable architecture allows customization of specific output frequencies within the supported range.
• LVDS differential output provides high-speed signal integrity suitable for demanding digital interfaces.
• Integrated enable/disable pin functionality facilitates power management and system state control.

Programmable Oscillators Applications

• High-performance computing systems requiring precise clock distribution
• Telecommunications infrastructure equipment
• Data acquisition and processing modules

Programmable Oscillators Procurement Notes

Verify the exact programmed frequency during procurement, as this value is unique to each unit and not fixed by the part number alone. Confirm that the 3.3V supply requirement aligns with the target design. Ensure the LVDS output compatibility matches the receiving circuitry specifications. Check lead times as these are custom-programmed components rather than standard off-the-shelf inventory items.

Programmable Oscillators Selection Notes

Select this model when a flexible, programmable clock source is required instead of a fixed-frequency oscillator. The Si591 series offers a compact footprint compared to larger discrete solutions. Consider the ±50 ppm stability specification against the jitter requirements of the downstream logic. Verify that the 7x5mm package dimensions fit within the available PCB real estate constraints.

Programmable Oscillators Part Context

This component belongs to the Si591 family of single-frequency oscillators manufactured by Skyworks Solutions. These devices are engineered to replace multiple fixed-frequency parts in inventory by allowing field or factory programming. The series targets applications needing reliable timing signals in space-constrained environments.

Programmable Oscillators Replacement Considerations

Direct parameter-equivalent substitutes include other Skyworks Si591 variants such as 591BB-CDG or 591BC-CDG, which share similar packaging and electrical characteristics but may differ in default stability or programming options. Cross-series replacements like the 530 series should be evaluated for pinout and voltage compatibility.
