SI5334C-B04088-GM

Overview

The SI5334C-B04088-GM is a pin-controlled quad clock generator from Skyworks Solutions. It synthesizes any frequency on four differential outputs using MultiSynth technology, achieving zero ppm frequency error and 0.7 ps RMS typical jitter. The device supports flexible input references including crystals (8–30 MHz) and clocks up to 710 MHz. Outputs are independently configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a core supply of 1.8, 2.5, or 3.3 V within the -40 to +85 °C range.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0.7 ps RMS typical jitter.
• Highly-configurable output drivers support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent voltage selection.
• Flexible input reference options include external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz).
• Pin-controlled configuration with factory programming via NVM; includes phase adjustment (<20 ps steps) and loss-of-lock/signal alarms.

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 'B04088' against the manufacturer's current ordering guide to confirm the exact frequency plan and package variant. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the selected part number matches the required output frequencies and signal formats defined in the design specifications.

Selection Notes

Select this component when low jitter and high flexibility are required for multi-standard clocking applications. Verify that the target output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Ensure the system power budget accommodates the typical 45 mA core supply current and individual output driver currents.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'C' suffix typically denotes a specific configuration variant within the series, distinct from other variants like 'M' which may include spread spectrum capabilities. The device is packaged in a 24-lead QFN (4x4 mm) suitable for space-constrained designs.

Replacement Considerations

Direct replacements must be sought from the Si5334 family with matching output configurations. Verify compatibility of pin assignments and control logic if substituting with other Si533x variants. Consult Skyworks Solutions for custom frequency plans if standard parts do not meet specific frequency requirements.
