SI5338N-B06142-GMR

Overview

The SI5338N-B06142-GMR 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 including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device accepts inputs up to 710 MHz via differential or single-ended interfaces. Key electrical parameters include a core supply voltage of 1.8 V, 2.5 V, or 3.3 V, with a typical operating current of 45 mA. It features low phase jitter of 0.7 ps RMS typ and operates within a temperature range of -40°C to +85°C in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with zero ppm accuracy.
• Supports highly configurable output formats: LVPECL/LVDS/CML (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), and SSTL/HSTL (up to 350 MHz).
• Features independent frequency increment/decrement for glitchless adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy.
• Includes I2C/SMBus compatible interface for programming and supports spread spectrum modulation with frequencies from 5 to 350 MHz.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant timing
• Ethernet switch/router and 1 GbE/10 GbE applications
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON systems

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B06142 suffix against the target design requirements. Confirm that the 24-QFN package dimensions and thermal characteristics align with the PCB land pattern specifications. Ensure the I2C pull-up voltages are compatible with the system bus levels, noting the requirement to write register 27 if the bus voltage is below 2.5 V.

Selection Notes

Select this component when multiple independent clock frequencies with low jitter are required from a single IC. Ensure the input reference source matches the supported formats, such as external crystals (8–30 MHz) or differential clocks (up to 710 MHz). Verify that the output driver supply voltages (1.5, 1.8, 2.5, or 3.3 V) match the load requirements for each specific output format.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' typically denotes a specific output configuration or speed grade, while the 'B06142' suffix indicates a custom factory-programmed NVM setting. The '-GMR' suffix denotes tape and reel packaging. It serves as a replacement for multiple discrete crystal oscillators in complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When replacing, ensure the new component supports the same I2C address and register map if software compatibility is required. Verify pin-to-pin compatibility for the 24-QFN package.
