SI5330K-B00226-GMR

Clock Buffers, Drivers Overview

The SI5330K-B00226-GMR is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions. It accepts a single-ended input signal and generates four differential LVPECL outputs at a 1:4 ratio. 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 the specified LVPECL format. Key electrical characteristics include a typical additive jitter of 150 fs RMS, an output-to-output skew of 100 ps, and a typical propagation delay of 2.5 ns. 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 LVPECL outputs
• Supports input frequencies from 5 to 350 MHz
• Features 150 fs typ additive jitter and 100 ps output skew
• 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 'GMR' indicates tape and reel shipment media as per standard Skyworks conventions. Confirm that the 2.5 V LVPECL output configuration matches the target system requirements. Check current availability status directly with the manufacturer or authorized distributors, as stock levels fluctuate.

Clock Buffers, Drivers Selection Notes

Select this part when a single-ended source must drive multiple LVPECL loads within the 350 MHz limit. Ensure the VDDO supply is regulated to 2.5 V. Verify that the input signal meets the single-ended voltage swing and rise/fall time specifications defined in the datasheet for reliable operation.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'K' designation identifies it as a single-ended input to differential output variant. The 'B' suffix typically denotes the 2.5 V output voltage level for the LVPECL format. The 'R' suffix specifies the reel packaging option.

Clock Buffers, Drivers Replacement Considerations

Other Si5330 variants such as SI5330K-B00224-GM provide similar functionality but with a 3.3 V LVPECL output. If the system requires 3.3 V outputs instead of 2.5 V, verify compatibility before substitution.
