SI5330L-B00229-GMR

Clock Buffers, Drivers Overview

The SI5330L-B00229-GMR is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions. It converts a single-ended input clock into four differential LVDS outputs. The device supports an input frequency range of 5 to 350 MHz and operates with a core supply voltage (VDD) of 1.8 V, 2.5 V, or 3.3 V. The output driver supply (VDDO) is set to 2.5 V for this specific part number. Key electrical characteristics include a typical propagation delay of 2.5 ns, output-output skew of 100 ps, and additive jitter of 150 fs RMS. It is housed in a 24-lead, 4 x 4 mm QFN package.

Clock Buffers, Drivers Feature Summary

• Converts single-ended input to four differential LVDS outputs
• Supports input frequencies from 5 to 350 MHz
• Low additive jitter: 150 fs RMS typical

• Ethernet Switch/Router
• SONET / SDH
• PCI Express 2.0/3.0
• Fibre Channel

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'GMR' indicates tape and reel packaging as per the datasheet. Confirm the output driver supply voltage requirement matches the system design, as this variant specifies 2.5 V LVDS outputs. Ensure the central ground pad is properly connected to the PCB ground plane for thermal management and signal integrity.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended clock source needs to drive multiple LVDS loads with low skew. The fixed 2.5 V output voltage distinguishes it from other Si5330 variants that support 1.8 V or 3.3 V LVDS. Verify that the input frequency does not exceed 350 MHz, as higher frequencies require different output formats like LVPECL.

Clock Buffers, Drivers Part Context

This part belongs to the Si5330 family of low-jitter clock buffers. The 'L' suffix denotes a single-ended input with differential LVDS outputs. The 'B00229' code specifies the 2.5 V output voltage configuration. The 'GMR' suffix indicates the device is shipped in tape and reel format for automated assembly.

Clock Buffers, Drivers Replacement Considerations

SI5330L-B00228-GM provides identical functionality but with 3.3 V LVDS outputs. SI5330L-B00230-GM offers 1.8 V LVDS outputs. For single-ended CMOS outputs, consider the Si5330F series.
