SI5330B-A00205-GM

Clock Buffers, Drivers Overview

The Si5330B-A00205-GM is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions Inc. It accepts differential input signals and generates four differential LVDS 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 LVDS compatibility. It supports an input frequency range of 5 to 710 MHz. Key electrical specifications include a typical additive phase jitter of 150 fs RMS (12 kHz–20 MHz), an output-to-output skew of 100 ps maximum, and a typical propagation delay of 2.5 ns.

Clock Buffers, Drivers Feature Summary

• Generates four differential LVDS outputs from a single differential input
• Supports wide frequency range from 5 MHz to 710 MHz
• Features low additive jitter of 150 fs RMS typical at 622.08 MHz
• Includes Loss of Signal (LOS) indicator and glitchless Output Enable (OEB)

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 the specific ordering suffix 'A00205' confirms the 2.5 V LVDS output configuration. Confirm package type is 24-lead QFN. Check for RoHS compliance status in current documentation. Ensure availability matches project requirements as component lifecycle status may vary.

Clock Buffers, Drivers Selection Notes

Select this part when differential LVDS outputs are required with a 2.5 V output driver supply. Ensure the input signal is differential; single-ended inputs require different variants like the Si5330L series. Verify that the 710 MHz maximum frequency meets system clock requirements. Consider power consumption if multiple units are used, as LVDS mode draws up to 8 mA per output buffer at 710 MHz.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'B' designation indicates LVDS output format. The 'A00205' code specifies the differential input and 2.5 V LVDS output configuration. It is distinct from CMOS, HCSL, or SSTL variants within the same package footprint.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the Si5330 family include Si5330B-A00204-GM (3.3 V LVDS) or Si5330B-A00206-GM (1.8 V LVDS) if output voltage levels differ. For single-ended inputs with LVDS outputs, consider Si5330L-A00229-GM. Pin-compatible alternatives from other manufacturers must be verified against electrical specifications.
