SI5338K-B06029-GMR

Overview

The SI5338K-B06029-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. Core supply voltage ranges from 1.71 V to 3.63 V (1.8 V, 2.5 V, or 3.3 V). Maximum input frequency is 710 MHz via differential inputs. Typical phase jitter is 0.7 ps RMS. Operating temperature spans -40 °C to +85 °C in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Low phase jitter of 0.7 ps RMS typical across LVPECL, LVDS, HCSL, and CML formats.
• Flexible input reference options: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), or differential (5–710 MHz).
• Independent glitchless frequency adjustment in 1 ppm steps and phase adjustment with <20 ps resolution.

Applications

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

Procurement Notes

Verify the specific factory configuration code embedded in the suffix B06029 against the official Skyworks ordering guide. This code defines the initial register map programmed into the internal non-volatile memory. Confirm that the required I2C address and output enable states match the system design requirements before procurement.

Selection Notes

Select this component when independent frequency synthesis for multiple domains is required within a single footprint. Ensure the target output format (LVPECL, LVDS, etc.) falls within the supported frequency range for that specific driver type. Verify that the input reference source matches one of the supported interface types, particularly if using high-speed differential inputs up to 710 MHz.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'K' designation typically indicates a specific factory-configured variant with pre-programmed parameters stored in OTP memory. The '-GMR' suffix denotes tape-and-reel packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants such as SI5338A, SI5338B, or SI5338Q series devices. However, functional equivalence requires matching the specific output frequencies and formats configured in the replacement part's NVM. Generic Si5338 devices may require reprogramming via I2C if they lack the specific factory preset.
