SI5338F-B04078-GM

Overview

The SI5338F-B04078-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, 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 true zero ppm accuracy on four output drivers.
• Low phase jitter performance of 0.7 ps RMS typ, compliant with PCIe Gen 1/2/3/4 Common Clock standards.
• Highly configurable output drivers supporting up to four differential outputs, eight single-ended outputs, or mixed configurations.
• Independent frequency increment/decrement feature allows glitchless adjustments in 1 ppm steps.

Applications

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

Procurement Notes

Verify the specific ordering suffix B04078 against the manufacturer's current documentation to confirm factory programming details. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling instructions during assembly.

Selection Notes

Select this component when low jitter (< 1 ps RMS) and high precision (0 ppm) are required for multiple independent clock domains. Verify that the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Confirm input reference frequency ranges align with available crystal or external clock sources.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It is designed to replace multiple discrete oscillators, reducing board space and power consumption. The device integrates a PLL and MultiSynth synthesizers within a compact 4x4 mm QFN-24 package.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the Si5338 series. Verify that substitute parts support the same output formats and jitter specifications required by the design.
