SI5338M-B10094-GM

Overview

The SI5338M-B10094-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers with 0 ppm precision. It operates within a core supply voltage range of 1.71 V to 3.63 V and supports frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical, flexible input references including differential inputs up to 710 MHz, and configurable output formats such as LVDS, LVPECL, HCSL, and CMOS. Packaged in a 24-lead QFN (4x4 mm), it enables glitchless frequency adjustments and independent phase control.

Feature Summary

• MultiSynth technology allows independent synthesis of any frequency on four outputs with true zero ppm accuracy
• Low phase jitter performance of 0.7 ps RMS typical across differential output drivers
• Flexible input support for external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential signals up to 710 MHz
• Independent output voltage configuration per driver at 1.5, 1.8, 2.5, or 3.3 V with highly configurable signal formats

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant timing
• Ethernet switch and router clocking
• Processor and FPGA clock generation
• Broadcast video and audio timing systems

Procurement Notes

Verify the specific ordering suffix B10094 against official Skyworks documentation to confirm pinout compatibility and factory programming settings. Ensure I2C/SMBus interface voltage levels match the system's logic requirements. Confirm thermal management strategies for the QFN-24 package under maximum load conditions.

Selection Notes

Select this component when replacing multiple crystal oscillators with a single programmable source is required. Ensure the application supports the 1.8 V, 2.5 V, or 3.3 V core supply options. Verify that the required output frequencies fall within the 0.16 MHz to 710 MHz range for the chosen output format.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It shares the MultiSynth architecture and general specifications with other variants like SI5338A and SI5338Q, differing primarily in factory-programmed frequency tables and specific ordering suffixes defined by Skyworks Solutions.

Replacement Considerations

Direct replacements must maintain the 24-QFN footprint and I2C interface. Verify that substitute parts support the same 710 MHz maximum input/output frequency and 0.7 ps jitter specifications if high-performance timing is critical.
