SI5330C-B00209-GMR

Clock Buffers, Drivers Overview

The SI5330C-B00209-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 (range 1.71 V to 1.98 V) and an independent output driver supply of 1.8 V. It supports input frequencies from 5 MHz to 250 MHz. 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, 4 x 4 mm QFN package.

Clock Buffers, Drivers Feature Summary

• Generates four differential HCSL outputs from a single differential input
• Additive jitter of 150 fs RMS typical at 12 kHz–20 MHz
• Output-output skew limited to 100 ps maximum
• Independent core (VDD) and output (VDDO) supply voltages

Clock Buffers, Drivers Applications

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

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'GMR' confirms tape and reel packaging as specified in the datasheet. Confirm the specific output format matches the application requirements for differential HCSL signals. Ensure the design accommodates the 1.8 V core and output supply constraints defined in the recommended operating conditions.

Clock Buffers, Drivers Selection Notes

Select this part when a differential input must be translated to four differential HCSL outputs. The fixed 1.8 V output configuration requires the receiving circuitry to support HCSL levels at this voltage. For other output formats like LVDS or LVPECL, or different supply voltages, consult the full Si5330 ordering table.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'C' designation indicates HCSL output drivers, while the 'B00209' code specifies the 1.8 V output supply configuration. The 'R' suffix denotes the reel packaging option for automated assembly.

Clock Buffers, Drivers Replacement Considerations

Other Si5330 variants with different output formats (e.g., Si5330A for LVPECL or Si5330B for LVDS) are pin-compatible but require different supply voltages and termination networks. Direct substitution requires verifying the output signal compatibility with the load.
