SI5340A-B03504-GMR

Overview

The SI5340A-B03504-GMR is a programmable clock generator from the Si5340 family, manufactured by Skyworks Solutions. It features four outputs capable of generating any frequency below 1028 MHz with ultra-low jitter performance specified at 90 fs. The device operates within a supply voltage range of 1.71 V to 3.47 V and supports multiple output interface types including CML, HCSL, LVCMOS, LVDS, and LVPECL. Packaged in a QFN-44 form factor for surface mount installation, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low jitter specification of 90 fs
• Four independent outputs supporting frequencies up to 1028 MHz
• Configurable output interfaces: CML, HCSL, LVCMOS, LVDS, LVPECL
• Single supply voltage operation between 1.71 V and 3.47 V

Applications

• High-speed data communication systems requiring precise clocking
• Telecommunications infrastructure equipment
• Industrial automation control units
• Test and measurement instrumentation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'GMR' indicates reel packaging versus tray variants. Check current lifecycle status as availability may be limited. Ensure ESD handling protocols are followed during storage and assembly due to moisture sensitivity classification.

Selection Notes

Select this model when low phase noise is critical for system timing integrity. Verify that the required output frequencies fall within the <1028 MHz limit. Ensure the design accommodates the QFN-44 thermal dissipation requirements. Compare against other Si5340 variants if different output counts or package styles are needed.

Part Context

This component belongs to the Si5340 MultiSynth family of clock generators. It shares core architecture with related models like SI5340A-D-GM but differs in configuration and packaging. The part is designed to replace older crystal oscillator solutions in high-performance applications demanding flexible frequency synthesis.

Replacement Considerations

Direct pin-to-pin replacements within the same family include SI5340A-D-GM for tray packaging. Cross-family alternatives require verification of jitter specs and output interface compatibility. Always validate electrical parameters against the original datasheet before substitution.
