SI5338J-B05415-GM

Overview

The SI5338J-B05415-GM 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 with formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply and accepts flexible input references up to 710 MHz. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum output frequency of 710 MHz for differential signals, and an operating temperature range of -40°C to +85°C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis with zero ppm accuracy on four output drivers.
• Supports highly configurable output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• Low phase jitter performance of 0.7 ps RMS typical.
• Flexible input reference options including external crystals (8-30 MHz), CMOS, SSTL/HSTL, and differential inputs.

Applications

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

Procurement Notes

Verify the specific factory programming configuration associated with the B05415 suffix against the system requirements. Confirm that the QFN-24 package dimensions align with the PCB land pattern specifications provided in the datasheet. Ensure I2C pull-up voltages are compatible with the selected core supply voltage.

Selection Notes

Select this component when multiple independent clock frequencies with low jitter are required from a single IC. Consider the output driver voltage requirements (1.5V, 1.8V, 2.5V, or 3.3V) for each channel. Verify that the input reference source matches the supported frequency ranges for the chosen input type (differential vs. single-ended).

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'J' designation typically indicates a specific factory-programmed configuration variant within the series. The '-GM' suffix denotes the tape and reel packaging format suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements must be from the Si5338 family with matching pinout and package. Verify that alternative part numbers support the same output formats and frequency ranges. Cross-reference the specific Bxxxxx configuration code to ensure functional equivalence without reprogramming.
