SI5330G-A00217-GM

Clock Buffers, Drivers Overview

The Si5330G-A00217-GM is a low-jitter, low-skew clock buffer and level translator from Silicon Laboratories. It accepts a differential input signal and generates eight single-ended CMOS 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 3.3 V for this specific part number. It supports frequency ranges up to 200 MHz for CMOS outputs. Key electrical characteristics include a typical additive jitter of 150 fs RMS (12 kHz–20 MHz), an output-to-output skew of 100 ps, and a typical propagation delay of 2.5 ns.

Clock Buffers, Drivers Feature Summary

• Generates eight single-ended CMOS outputs from a differential input
• Additive phase jitter of 150 fs RMS typ (12 kHz–20 MHz)
• Output-output skew of 100 ps max
• Independent core (VDD) and output (VDDO) supply voltages

Clock Buffers, Drivers Applications

• High-speed clock distribution
• Ethernet Switch/Router
• PCI Express 2.0/3.0 systems

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'GM' indicates a lead-free, RoHS-compliant package in tape and reel format if required by assembly processes. Confirm that the 3.3 V output voltage requirement matches the receiving logic levels. Ensure the differential input signal specifications align with the device's AC-coupled input requirements.

Clock Buffers, Drivers Selection Notes

Select this part when a differential source must drive multiple single-ended CMOS loads. The independent VDDO supply allows flexibility in setting output swing levels, though this specific variant is fixed at 3.3 V. Consider the 24-lead 4x4 mm QFN package constraints for PCB layout. Verify that the input frequency does not exceed 200 MHz for CMOS operation.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of clock buffers. The 'G' suffix designates a differential input to single-ended CMOS configuration. Other variants in the family support LVPECL, LVDS, HCSL, SSTL, and HSTL outputs, or single-ended inputs. This specific model is optimized for high-volume digital systems requiring fan-out from a differential reference.

Clock Buffers, Drivers Replacement Considerations

Direct functional replacements within the same family include Si5330G-A00218-GM (2.5 V CMOS outputs) and Si5330G-A00219-GM (1.8 V CMOS outputs). For different input/output configurations, consult Table 11 in the datasheet for compatible part numbers such as Si5330F series for single-ended inputs.
