SI5330G-B00219-GMR

Clock Buffers, Drivers Overview

The SI5330G-B00219-GMR is a low-jitter, low-skew clock buffer and level translator from Skyworks Solutions. It accepts a differential input clock and generates eight single-ended CMOS outputs. The device operates with a core supply voltage of 1.8 V (range 1.71–1.98 V) and an independent output driver supply of 1.8 V. 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), output-to-output skew of 100 ps, and typical propagation delay of 2.5 ns. The component is housed in a 24-lead 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)
• Independent core (VDD) and output (VDDO) supply voltages
• 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

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'GMR' corresponds to tape-and-reel shipment media as specified in the datasheet. Confirm that the specific part number matches the required 1.8 V output voltage configuration. Ensure the source documentation explicitly identifies this part as a differential-input, single-ended-output device.

Clock Buffers, Drivers Selection Notes

Select this part when a differential input signal must be converted to eight single-ended CMOS clocks. The 1.8 V output voltage rating requires the VDDO pins to be powered at 1.8 V. Verify that the application frequency does not exceed 200 MHz for CMOS output formats. Check if the 24-lead QFN package dimensions fit the PCB layout constraints.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of universal clock buffers. The 'G' designation indicates a differential input with single-ended outputs. The 'B00219' code specifies the 1.8 V output voltage variant. The 'R' suffix denotes tape-and-reel packaging, distinguishing it from the tray-packaged 'GM' version.

Clock Buffers, Drivers Replacement Considerations

SI5330G-B00218-GM provides identical functionality but operates with a 2.5 V output voltage. SI5330G-B00217-GM offers the same configuration with a 3.3 V output voltage. Ensure the replacement's output supply voltage matches the target circuit requirements.
