SI5330H-B00221-GM

Clock Buffers, Drivers Overview

The SI5330H-B00221-GM is a low-jitter, low-skew clock buffer and level translator from Skyworks Solutions. It accepts a differential input signal and generates eight single-ended SSTL outputs. The device supports an input frequency range of 5 to 350 MHz. It operates with a core supply voltage (VDD) of 2.5 V ±10% and an independent output driver supply (VDDO) of 2.5 V ±10%. Key electrical characteristics include a typical additive phase jitter of 150 fs RMS (12 kHz–20 MHz), a maximum 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
• Supports input frequencies up to 350 MHz
• Features 150 fs typ additive jitter and 100 ps max output skew
• Includes Loss of Signal (LOS) indicator and glitchless Output Enable (OEB)

Clock Buffers, Drivers Applications

• High-speed clock distribution
• Ethernet switch/router systems
• PCI Express 2.0/3.0 interfaces

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm shipment media and any recent product change notifications. Confirm that the required output supply voltage matches the 2.5 V specification for this variant. Ensure PCB layout guidelines for the 24-lead QFN package are followed to maintain signal integrity.

Clock Buffers, Drivers Selection Notes

Select this part when a differential input source must be translated to eight single-ended SSTL loads. Verify that the target SSTL standard (SSTL-2 or SSTL-3) aligns with the 2.5 V output supply configuration. Consider the 350 MHz maximum frequency limit relative to the system clock requirements.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'H' designation indicates the SSTL output format, while the 'B00221' suffix specifies the 2.5 V output supply voltage and differential input configuration within the Si5330H series.

Clock Buffers, Drivers Replacement Considerations

Other Si5330 variants such as SI5330H-B00220-GM (3.3 V SSTL) or SI5330H-B00222-GM (1.8 V SSTL) share the same package and functional block but differ in output voltage levels. Direct substitution requires verifying output driver supply compatibility.
