SI5334C-B04811-GM

Overview

The SI5334C-B04811-GM is a pin-controlled quad clock generator utilizing MultiSynth technology for independent, any-frequency synthesis on four differential outputs. It supports input frequencies from 5 to 710 MHz and generates output frequencies up to 350 MHz generally, with select frequencies reaching 710 MHz. The device achieves zero ppm frequency accuracy and typical phase jitter of 0.7 ps RMS. It operates on a core supply voltage of 1.8 V, 2.5 V, or 3.3 V, with independently configurable output driver voltages ranging from 1.5 V to 3.3 V. Packaged in a 24-lead QFN (4x4 mm) format, it functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• MultiSynth Technology: Enables independent, any-frequency synthesis on four differential outputs with zero ppm frequency error.
• Flexible Output Drivers: Supports LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent output voltage selection (1.5V, 1.8V, 2.5V, or 3.3V).
• Low Phase Jitter: Typical RMS jitter of 0.7 ps across all outputs.
• Pin-Controlled Operation: Factory-programmable configuration without I2C interface; includes LOS/LOL alarm and OEB pin.

Applications

• Ethernet switch/router clocking
• PCI Express 2.0/3.0 timing
• Processor and FPGA clock generation
• Broadcast video/audio synchronization

Procurement Notes

Verify the specific suffix 'B04811' against the manufacturer's current ordering guide to confirm the exact factory-programmed frequency plan. Ensure the package type matches the required 24-QFN footprint and that the core supply voltage aligns with the system design constraints of 1.8V, 2.5V, or 3.3V.

Selection Notes

Select this component when independent frequency synthesis on four outputs is required without digital interface complexity. Confirm that the target output frequencies fall within the 350 MHz general limit or the 710 MHz selective limit. Verify that the required output signal formats (e.g., LVDS, LVPECL) are supported by the specific output drivers assigned in the configuration.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'C' designation typically indicates specific feature sets or revision levels within the series, while the alphanumeric suffix defines the unique frequency plan programmed into the internal non-volatile memory at the factory.

Replacement Considerations

Direct replacements must be from the Si5334 family with identical pinouts and electrical characteristics. Verify that alternative part numbers support the same output formats and frequency ranges. Cross-reference the specific frequency plan requirements to ensure functional equivalence.
