SI5338M-B04370-GM

Overview

The SI5338M-B04370-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is managed via an I²C/SMBus interface, allowing for flexible input references including crystals, CMOS, and differential clocks.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliance.
• Flexible output drivers configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats.
• Low phase jitter of 0.7 ps RMS typical with independent output voltage options (1.5, 1.8, 2.5, or 3.3 V).

Applications

• PCIe Gen1/2/3/4 systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix B04370 against official Skyworks documentation to confirm the programmed frequency plan and pinout configuration. Ensure compatibility with the required I²C address and output signal formats before integration. Check for moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single package. Verify that the required output frequencies fall within the supported ranges for the chosen output format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Confirm that the input reference source matches the supported types: external crystal (8-30 MHz), CMOS (5-200 MHz), or differential (5-710 MHz).

Part Context

This part belongs to the Si5338 family of I²C-programmable any-frequency, any-output quad clock generators. The 'M' in the part number typically denotes a specific factory-programmed configuration variant within the series, distinct from user-programmable variants like the 'A' or 'Q'.

Replacement Considerations

Direct replacements must be from the Si5338 family with compatible programming configurations. Verify that substitute parts support the same output frequencies, signal formats, and package type (24-QFN). Cross-reference with Skyworks ClockBuilder Pro software to ensure functional equivalence.
