SI5338C-B05574-GM

Overview

The SI5338C-B05574-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS typ, zero ppm frequency accuracy, and an I2C/SMBus interface for configuration.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers
• Supports flexible input references: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential (5-710 MHz)
• Highly configurable outputs support various signal formats and independent voltage levels (1.5, 1.8, 2.5, or 3.3 V)
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy

Applications

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

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B05574 suffix against the system requirements. Confirm that the QFN-24 package land pattern matches the recommended PCB layout provided in the datasheet. Ensure the I2C pull-up voltages are compatible with the selected core supply voltage.

Selection Notes

Select this component when multiple independent clock frequencies with precise phase relationships are required. Verify that the input reference source matches the supported frequency ranges for the chosen format. Check if the output drive strength and voltage levels meet the load requirements of the destination devices.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' indicates a specific performance grade or feature set within the series, while the 'B05574' suffix denotes a unique factory-programmed configuration stored in non-volatile memory. The 'GM' suffix typically indicates a tape-and-reel packaging option.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory programming. Ensure the replacement part supports the required output frequencies and formats. Cross-model compatibility should be validated using the ClockBuilder Pro software.
