SI5338B-B06189-GM

Overview

The SI5338B-B06189-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis on four output drivers. It supports any frequency up to 710 MHz with zero ppm precision and features low phase jitter of 0.7 ps RMS typical. The device accepts various input references including differential clocks up to 710 MHz and operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V. Outputs are configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, housed in a compact 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Low phase jitter performance of 0.7 ps RMS typical across all outputs.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (up to 710 MHz).
• Independently configurable output drivers supporting multiple signal formats and supply voltages (1.5, 1.8, 2.5, or 3.3 V).

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant timing.
• Ethernet switch/router clocking.
• Processor and FPGA clocking.
• Broadcast video/audio timing.

Procurement Notes

Verify the specific B06189 factory code against the manufacturer's current ordering guide to confirm availability and revision status. Ensure I2C pull-up voltage compatibility if operating below 2.5 V by checking register settings. Confirm moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this model for applications requiring high-precision, glitch-free frequency adjustments and independent phase control on each output. Verify that the required output frequencies fall within the supported ranges for the chosen signal format, particularly noting limits for CMOS (200 MHz) versus LVDS/LVPECL (710 MHz). Ensure the design accommodates the 45 mA typical core supply current.

Part Context

This component belongs to the Si5338 family of I2C-programmable clock generators. The 'B' suffix typically denotes specific frequency configurations or output capabilities distinct from other variants like the 'A' or 'Q' series. The 'GM' suffix indicates the QFN-24 package type and lead-free composition.

Replacement Considerations

Direct pin-to-pin replacements within the same family include SI5338A and SI5338Q variants, provided their specific frequency constraints and output format limitations align with the system requirements. Verify register compatibility when migrating between different factory codes within the Si5338 series.
