SI5338A-B05922-GMR

Overview

The SI5338A-B05922-GMR is a programmable clock generator utilizing MultiSynth technology to synthesize any frequency on four output drivers. It supports differential outputs up to 710 MHz and single-ended formats including CMOS (up to 200 MHz), HCSL (up to 250 MHz), and SSTL/HSTL (up to 350 MHz). The device operates from a 1.8, 2.5, or 3.3 V core supply with independent output voltage configurations of 1.5, 1.8, 2.5, or 3.3 V. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum input frequency of 710 MHz, and a typical core supply current of 45 mA.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with zero ppm precision.
• Low phase jitter performance of 0.7 ps RMS typ, compliant with PCIe Gen 1/2/3/4 Common Clock standards.
• Highly configurable output drivers supporting LVPECL/LVDS (up to 710 MHz), HCSL, CMOS, SSTL, and HSTL formats.
• Independent frequency increment/decrement feature allows glitchless adjustments in 1 ppm steps.

Applications

• PCIe Gen 1/2/3/4 systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Fibre Channel and SAN applications

Procurement Notes

Verify the specific factory configuration code B05922 against the official Skyworks ordering guide to ensure correct frequency and format settings. Confirm that the GMR suffix indicates tape-and-reel packaging compatible with automated assembly processes. Cross-reference the datasheet revision date to ensure compliance with current manufacturing specifications.

Selection Notes

Select this component when designing systems requiring low-jitter clock generation for high-speed interfaces like PCIe or Ethernet. Ensure the required output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz). Verify that the available input reference sources match the device's flexible input requirements, including external crystals or differential CMOS inputs.

Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. The 'A' designation typically refers to the silicon grade or specific performance bin, while 'B05922' represents the unique factory configuration defining the output frequencies and formats. The 'GMR' suffix denotes the standard reel packaging format used for surface-mount assembly.

Replacement Considerations

Direct replacements within the same package and pinout include other Si5338 variants such as SI5338Q-B-GMR or SI5338A-Bxxxxx-GMR. When substituting, verify that the new part number matches the required output frequencies and signal formats, as these are hard-coded during manufacturing.
