SI5340A-B03285-GMR

Overview

The SI5340A-B03285-GMR is a programmable clock generator from Skyworks Solutions, part of the Si5340 family. 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 format 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 under 1028 MHz
• Flexible output interface options: CML, HCSL, LVCMOS, LVDS, LVPECL
• Operates on 1.8 V or 3.3 V power supplies

Applications

• High-speed data communication systems
• Telecommunications infrastructure equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'GMR' against official Skyworks documentation to confirm tape-and-reel packaging status, as datasheets may primarily list tray-packaged variants like 'GM'. Confirm end-of-life status and availability through authorized distributors, as this component may be discontinued or subject to limited supply constraints.

Selection Notes

Select this model when low jitter and flexible output formatting are required for four distinct clock signals. Ensure the design accommodates the QFN-44 package thermal requirements. Verify that the input frequency does not exceed 750 MHz and that the target output frequencies remain below the 1028 MHz maximum limit defined by the silicon capabilities.

Part Context

This component belongs to the Si5340 series of MultiSynth clock generators. It shares core architectural similarities with other models in the family, such as the SI5340A-D-GM, differing primarily in factory-programmed configuration parameters and packaging type. The series is designed for applications demanding precise timing synchronization without external crystal dependencies.
