SI5330B-B00205-GM

Clock Buffers, Drivers Overview

The SI5330B-B00205-GM is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions. It accepts differential input signals and generates four differential LVDS outputs at a 2.5 V logic level. The device supports an input frequency range of 5 to 710 MHz with a typical additive phase jitter of 150 fs RMS (12 kHz–20 MHz). It operates on a single core supply voltage of 1.8, 2.5, or 3.3 V, while the output driver supply is independently set to 2.5 V. Key electrical parameters include a maximum propagation delay of 4.0 ns, output-output skew of 100 ps, and a typical core supply current of 10 mA.

Clock Buffers, Drivers Feature Summary

• Generates four differential LVDS outputs from a single differential input
• Supports input frequencies up to 710 MHz with 150 fs typ. additive jitter
• Independent core (VDD) and output (VDDO) supply voltages for flexibility
• Includes Loss of Signal (LOS) indicator and glitchless Output Enable (OEB)

Clock Buffers, Drivers Applications

• High-speed clock distribution
• Ethernet Switch/Router
• SONET / SDH systems
• PCI Express 2.0/3.0 interfaces

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact input/output configuration and shipment media. The standard part number denotes tray packaging; adding an 'R' suffix indicates tape and reel shipping. Confirm RoHS compliance status through the manufacturer's product certificates prior to procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a differential-to-differential translation to 2.5 V LVDS is required. Ensure the system design provides a separate 2.5 V supply for the VDDO pins to drive the LVDS outputs correctly. Verify that the input signal frequency falls within the 5 to 710 MHz range and that the PCB layout adheres to the recommended land pattern for the 24-lead QFN package.

Clock Buffers, Drivers Part Context

This device belongs to the Si5330 family of low-jitter clock buffers. The 'B' in the part number identifies it as the variant configured for differential inputs and differential LVDS outputs. Other variants in the series support different output formats such as CMOS, HCSL, or LVPECL, or accept single-ended inputs.
