SI5338C-B04853-GM

Overview

The SI5338C-B04853-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis. It supports four output drivers with configurable formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and accepts differential inputs up to 710 MHz. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum output frequency of 710 MHz, and an operating temperature range of -40°C to +85°C.

Feature Summary

• MultiSynth technology enables zero ppm precision and glitchless frequency adjustments.
• Supports flexible input references: external crystals (8-30 MHz), CMOS (5-200 MHz), and differential signals (up to 710 MHz).
• Configurable output drivers support any frequency within format limits and independent voltage levels (1.5V, 1.8V, 2.5V, 3.3V).
• Integrated I2C/SMBus interface allows programming via ClockBuilder Pro software.

Applications

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

Procurement Notes

Verify the specific suffix 'B04853' against the manufacturer's current ordering guide to confirm factory configuration and availability status. Check RoHS compliance details and moisture sensitivity levels before integration into production lines.

Selection Notes

Select this component when low jitter (<1 ps RMS) and high flexibility in output formats are required. Ensure the design accommodates the QFN-24 package thermal requirements and provides appropriate termination for the chosen differential or single-ended output standards.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' designation typically indicates specific performance grades or output configurations within the series, while the alphanumeric suffix defines the pre-programmed register settings for immediate deployment.

Replacement Considerations

Direct pin-to-pin replacements within the same family include SI5338A-B-GM and SI5338N-B-GMR. Verify that the substitute part supports the required output frequencies and signal formats, as performance metrics like jitter may vary between variants.
