591MD-ADG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 591MD-ADG is a programmable crystal oscillator (XO) from the Si591 series, designed for high-performance clocking applications. It operates on a single 3.3V supply voltage and features an LVPECL output format. The device supports a frequency range of 10MHz to 124.999MHz with a frequency stability of ±7ppm and overall stability of ±20ppm. It is housed in a compact 6-SMD, no-lead package measuring 7.00mm x 5.00mm x 1.80mm. The component includes enable/disable functionality and operates within a temperature range of -40°C to 85°C.

Programmable Oscillators Feature Summary

• Programmable frequency generation within the 10MHz to 124.999MHz range using Digi-Key programming services.
• LVPECL output interface providing differential signaling for high-speed digital systems.
• Integrated enable and disable control function for power management flexibility.

Programmable Oscillators Applications

• High-speed data communication interfaces requiring precise clock synchronization.
• Telecommunications equipment utilizing LVPECL compatible components.
• Test and measurement instruments demanding low phase noise and stable frequency references.

Programmable Oscillators Procurement Notes

This part requires specific frequency programming at the time of order through authorized distributors like Digi-Key. Verify that the requested frequency falls within the supported 10MHz to 124.999MHz range. Confirm the LVPECL output type matches your system design. Ensure the 3.3V supply voltage aligns with your board's power architecture before placing orders.

Programmable Oscillators Selection Notes

Select this model when a programmable XO with LVPECL outputs is required for frequencies up to 124.999MHz. The ±7ppm stability suits applications needing tighter tolerance than standard oscillators. Consider the 6-SMD package size for space-constrained designs. Compare against fixed-frequency alternatives if programming lead times are unacceptable or if lower cost non-programmable variants suffice for the application.

Programmable Oscillators Part Context

The 591MD-ADG belongs to the Skyworks Si591 family of surface-mount programmable oscillators. This series offers various output formats and frequency ranges. The MD suffix typically indicates specific packaging or programming configurations within the product line. It serves as a flexible timing solution replacing multiple fixed-frequency crystals in complex electronic systems.

Programmable Oscillators Replacement Considerations

Direct parameter-equivalent replacements may include other Si591 models with matching LVPECL outputs and similar frequency ranges. Verify pin compatibility and electrical specifications such as supply voltage and current consumption. Consult distributor databases for cross-references based on exact frequency requirements and package dimensions.
