SI5330K-B00224-GM

Clock Buffers, Drivers Overview

The SI5330K-B00224-GM 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. The device supports a frequency range of 5 to 350 MHz with an additive jitter of 150 fs RMS typical. It operates on a single core supply voltage of 1.8, 2.5, or 3.3 V, while the output driver supply is independently set to 3.3 V. Key features include glitchless output enable control via the OEB pin, a loss-of-signal indicator, and operation within the industrial temperature range of –40 to +85 °C.

Clock Buffers, Drivers Feature Summary

• Converts single-ended input to four differential LVPECL outputs
• Frequency range of 5 to 350 MHz with 150 fs RMS typical additive jitter
• Independent core (1.8/2.5/3.3 V) and output (3.3 V) supply voltages
• Glitchless output enable and loss-of-signal monitoring

Clock Buffers, Drivers Applications

• High-speed clock distribution
• Ethernet switch/router systems
• SONET/SDH networks
• PCI Express 2.0/3.0 interfaces
• Fibre Channel connections

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix B00224 to confirm the single-ended input and 3.3 V LVPECL output configuration. Ensure the design accommodates the 24-lead QFN package requirements, including proper grounding of the center pad. Confirm that the application voltage levels align with the specified core and output supply ranges before procurement.

Clock Buffers, Drivers Selection Notes

Select this part when a single-ended clock source must be distributed to four LVPECL loads. Verify that the required frequency does not exceed 350 MHz. If differential input is needed, consider the Si5330A/B/C variants. Ensure the output supply voltage matches the 3.3 V requirement for the LVPECL drivers.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'K' designation indicates single-ended input functionality, distinguishing it from the 'A', 'B', and 'C' variants which accept differential inputs. The 'B00224' suffix specifies the 3.3 V LVPECL output format.

Clock Buffers, Drivers Replacement Considerations

Si5330K-B00226-GM provides identical functionality but operates with a 2.5 V LVPECL output supply.
