SI5330H-B00220-GMR

Clock Buffers, Drivers Overview

The SI5330H-B00220-GMR is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions. It accepts a differential input clock signal and generates eight single-ended SSTL 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 independently set to 3.3 V for SSTL compatibility. It supports input frequencies from 5 MHz to 350 MHz. 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 SSTL outputs from a differential input clock
• 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
• SONET/SDH systems
• PCI Express 2.0/3.0 interfaces
• Fibre Channel applications

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'GMR' indicates tape and reel shipment media as specified in the datasheet. Confirm the specific output voltage configuration matches the application requirements, as the 'H' variant is designated for 3.3 V SSTL outputs. Ensure the central ground pad is properly connected to the system ground plane during assembly to maintain specified performance.

Clock Buffers, Drivers Selection Notes

Select this part when a differential input source must drive eight single-ended SSTL loads. The independent VDDO supply allows flexibility in setting output levels, but this specific model is fixed for 3.3 V SSTL. Consider the Si5330H-B00221-GMR or Si5330H-B00222-GMR if lower output voltage levels (2.5 V or 1.8 V SSTL) are required instead.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'H' designation identifies it as a differential-input, single-ended-output device configured for SSTL signaling. The 'B00220' code specifies the 3.3 V SSTL output variant. The 'R' suffix denotes the tape and reel packaging format, distinguishing it from the tray-packaged 'GM' version.

Clock Buffers, Drivers Replacement Considerations

Si5330H-B00221-GMR provides identical functionality with 2.5 V SSTL outputs. Si5330H-B00222-GMR provides identical functionality with 1.8 V SSTL outputs. For non-reel packaging, the 'GM' suffix variants (e.g., SI5330H-B00220-GM) are available.
