591FD-CDG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 591FD-CDG is a programmable crystal oscillator (XO) from the Si591 series, designed for high-performance clocking applications. It features an LVDS output format and operates on a 2.5V supply voltage. The device offers a frequency stability of ±7 ppm and supports frequencies within the 10 MHz to 810 MHz range. It is housed in a compact 6-SMD, no-lead package measuring 7 mm x 5 mm with a maximum height of 1.80 mm. The component includes an enable/disable function and operates within a temperature range of -40°C to +85°C.

Programmable Oscillators Feature Summary

• Programmable architecture allows customization of specific frequency outputs across a wide operational range.
• LVDS differential output format provides robust signal integrity for high-speed digital interfaces.
• Integrated enable/disable pin functionality facilitates power management and system synchronization control.

Programmable Oscillators Applications

• High-speed data communication systems requiring precise timing references
• Network infrastructure equipment such as routers and switches
• Test and measurement instruments demanding low phase noise performance

Programmable Oscillators Procurement Notes

Verify the exact target frequency configuration during procurement, as this is a programmable part. Confirm that the required programming tool or service is available, as blank units require specific setup before deployment. Ensure the LVDS output compatibility matches the receiving circuitry design specifications.

Programmable Oscillators Selection Notes

Select this model when a flexible, single-frequency general-purpose oscillator is needed with LVDS outputs. The ±7 ppm stability suits applications tighter than standard general-purpose oscillators but less critical than oven-controlled types. Consider the 7x5mm footprint for board space constraints compared to smaller family members.

Programmable Oscillators Part Context

This component belongs to the Si591 series of standard clock oscillators by Skyworks Solutions. It shares the same physical package dimensions and basic interface characteristics with other parts in the series, differing primarily in internal programmability settings and specific electrical parameters like stability and current consumption.

Programmable Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As a programmable device, direct pin-to-pin replacements may require reprogramming or configuration adjustments to match the original frequency and protocol requirements.
