SI5338B-B04160-GMR

Overview

The SI5338B-B04160-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 formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates with a core supply of 1.8 V, 2.5 V, or 3.3 V and accepts inputs up to 710 MHz. Key electrical parameters include a typical RMS jitter of 0.7 ps, a maximum input frequency of 710 MHz, and an operating temperature range of -40°C to +85°C.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis with zero ppm precision on four outputs.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential (5–710 MHz).
• Configurable output drivers support various signal formats and independent supply voltages (1.5, 1.8, 2.5, or 3.3 V).
• Features glitchless frequency adjustments via independent increment/decrement pins and spread spectrum generation.

Applications

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

Procurement Notes

Verify the specific B04160 factory configuration against the datasheet's ordering information table to ensure correct pinout and NVM programming. Confirm that the QFN-24 package thermal characteristics meet the system's heat dissipation requirements. Check for moisture sensitivity level compliance during storage and reflow soldering processes.

Selection Notes

Select this component when low-jitter (< 1 ps RMS) multi-output clock generation is required. Ensure the target application utilizes compatible output voltage levels (LVPECL, LVDS, etc.) supported by the Si5338 family. Use ClockBuilder Pro software to configure the I2C registers and validate phase noise performance for the specific frequency plan.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators in complex digital systems. The 'B' suffix indicates a specific factory-programmed configuration variant within the broader Si5338 product line, distinguished by its pre-loaded NVM settings.

Replacement Considerations

Direct replacements within the same family include other Si5338 variants with different factory configurations (e.g., SI5338A, SI5338Q). Verify that the substitute part number matches the required output frequencies and formats defined in the original design specifications.
