SI5330G-B00218-GMR

Clock Buffers, Drivers Overview

The SI5330G-B00218-GMR is a low-jitter, low-skew clock buffer and level translator from Skyworks Solutions. It accepts a differential input clock signal and generates eight single-ended CMOS outputs. The device operates with a core supply voltage of 1.8 V, 2.5 V, or 3.3 V, while the output driver supply (VDDO) is set to 2.5 V for this specific part number. It supports input frequencies up to 200 MHz for CMOS outputs. Key electrical characteristics include a typical additive phase jitter of 150 fs RMS (12 kHz–20 MHz), an output-to-output skew of 100 ps, and a typical propagation delay of 2.5 ns. The component is housed in a 24-lead, 4 x 4 mm QFN package.

Clock Buffers, Drivers Feature Summary

• Generates eight single-ended CMOS outputs from a differential input
• Low additive jitter: 150 fs RMS typical (12 kHz–20 MHz)
• Output-output skew: 100 ps maximum
• Independent core (VDD) and output (VDDO) supply voltages

Clock Buffers, Drivers Applications

• High-speed clock distribution
• Ethernet switch/router
• PCI Express 2.0/3.0
• Fibre Channel

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'R' indicates tape and reel shipment media as per manufacturer documentation. Confirm that the B00218 designation corresponds to the 2.5 V output driver supply configuration. Ensure compatibility with the required 24-lead QFN land pattern dimensions specified in the datasheet.

Clock Buffers, Drivers Selection Notes

Select this part when a differential input source must be converted to eight single-ended CMOS loads. The VDDO supply must be connected to 2.5 V to meet the output specifications. Verify that the input frequency does not exceed 200 MHz for CMOS operation. The OEB pin allows glitchless output enable/disable control.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'G' suffix identifies it as a differential-input, single-ended-output variant. The 'B00218' code specifies the 2.5 V output voltage setting. The 'R' suffix denotes the tape and reel packaging format.

Clock Buffers, Drivers Replacement Considerations

Other Si5330 variants with different output counts or voltage settings may serve as alternatives if the application permits changes to fanout or I/O levels. Consult the manufacturer's ordering guide for compatible parts with matching input/output configurations.
