SI5338A-B09174-GMR

Overview

The SI5338A-B09174-GMR is an I2C-programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports a core supply of 1.8, 2.5, or 3.3 V and operates within a temperature range of –40 to +85 °C. Key electrical parameters include a maximum input frequency of 710 MHz and typical phase jitter of 0.7 ps RMS. Outputs support LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Low phase jitter of 0.7 ps RMS typical.
• Flexible input reference supporting external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Independent output voltage per driver: 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 B09174 factory code against the manufacturer's current ordering guide to confirm the programmed frequency configuration. Ensure the GMR suffix matches the required tape-and-reel packaging format for automated assembly processes.

Selection Notes

Select this component when low-jitter synthesis is required for high-speed interfaces like PCIe or Ethernet. Confirm that the target output frequencies fall within the supported ranges for the desired signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz) and that the I2C interface is compatible with the system controller.

Part Context

This part belongs to the Si5338 family of programmable clock generators from Skyworks Solutions. The 'A' designation typically indicates the 710 MHz performance grade, while the alphanumeric suffix defines the specific factory programming configuration.

Replacement Considerations

Direct pin-to-pin replacements within the same package require identical frequency configurations. Verify compatibility with alternative SKUs such as SI5338A-B-GM or SI5338N-B-GMR, ensuring their pre-programmed settings match the design requirements.
