SI5330C-B00208-GMR

Clock Buffers, Drivers Overview

The SI5330C-B00208-GMR is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions Inc. It accepts a differential input signal and generates four differential HCSL 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 2.5 V for HCSL compatibility. It supports an input frequency range of 5 to 710 MHz and an output frequency range of 5 to 250 MHz. Key electrical characteristics include a typical additive jitter of 150 fs RMS, 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 four differential HCSL outputs from a single differential input
• Additive phase jitter of 150 fs RMS (typical)
• Output-to-output skew of 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' corresponds to tape and reel packaging as specified in the datasheet. Confirm the specific output voltage configuration matches the system requirements, as the 'B00208' suffix indicates a 2.5 V output driver supply. Ensure the central ground pad is properly connected to the PCB ground plane for correct operation.

Clock Buffers, Drivers Selection Notes

Select this part when a differential input must be translated to four differential HCSL outputs. The VDDO supply pin must be connected to 2.5 V to achieve the specified HCSL voltage levels. Verify that the input signal format is compatible with the differential pins IN1 and IN2. Consider the 10 mA typical core current for power budgeting.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'C' designation identifies it as an HCSL output variant. The 'B00208' code specifies the differential input and 2.5 V HCSL output configuration. The 'R' suffix denotes the tape and reel shipping method, distinguishing it from the tray-packaged 'GM' version.
