SI5330J-B00223-GM

Clock Buffers, Drivers Overview

The SI5330J-B00223-GM is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions. It accepts a differential input signal and generates eight single-ended HSTL 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 set to 1.5 V for HSTL compatibility. Key electrical parameters include a typical additive phase 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. The component supports frequency ranges from 5 to 350 MHz and functions within an industrial temperature range of –40 to +85 °C.

Clock Buffers, Drivers Feature Summary

• Generates eight single-ended HSTL outputs from a differential input
• Additive jitter of 150 fs RMS typical at 622.08 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 networks
• Ethernet switch and router systems
• SONET/SDH infrastructure
• PCI Express 2.0/3.0 interfaces
• Fibre Channel connections

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix to confirm shipment media; adding an 'R' to the part number indicates tape and reel packaging. Confirm that the system design accommodates the required 1.5 V output driver supply voltage for proper HSTL signal levels. Ensure the central ground pad is connected to the main ground plane using multiple vias to maintain specified thermal and electrical performance.

Clock Buffers, Drivers Selection Notes

Select this part when a differential input source must be converted to eight single-ended HSTL loads. The independent VDDO supply allows flexibility in setting output voltage levels separate from the core logic supply. Verify that the input clock frequency falls within the 5 to 350 MHz range supported by the HSTL output format. Consider the 24-lead QFN package dimensions for PCB layout constraints.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'J' suffix specifically denotes the configuration with differential input and eight single-ended HSTL outputs. Other variants in the series support different output formats such as LVPECL, LVDS, CMOS, and SSTL, or accept single-ended inputs.

Clock Buffers, Drivers Replacement Considerations

Direct functional substitutes within the same family include other Si5330 variants with matching input/output configurations, such as Si5330H-B00220-GM for SSTL outputs. For identical HSTL functionality, verify availability of Si5330J-B00223-GMR for tape-and-reel packaging requirements.
