SI5334C-B04088-GMR

Overview

The SI5334C-B04088-GMR 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 an industrial temperature range of –40 to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with low phase jitter.
• Highly-configurable output drivers support up to four differential outputs or eight single-ended clock outputs.
• Flexible input reference options include external crystals (8 to 30 MHz), CMOS, SSTL/HSTL, and differential inputs.
• Independent output voltage per driver allows 1.5, 1.8, 2.5, or 3.3 V selection.

Applications

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

Procurement Notes

Verify the specific factory-programmed frequency plan associated with the B04088 suffix against system requirements. Confirm that the required output signal formats and frequencies align with the device's electrical specifications. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this model when pin control is preferred over I2C programming. Verify that the target frequencies fall within the supported ranges: up to 350 MHz for standard synthesis and select frequencies up to 710 MHz. Ensure the application can accommodate the 4x4 mm QFN-24 package dimensions and thermal characteristics.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'C' in the part number denotes a specific configuration variant within the series, while the 'GMR' suffix indicates tape-and-reel packaging. The device utilizes patented MultiSynth technology for high-precision frequency synthesis.

Replacement Considerations

Direct replacements must be sought from the Si5334 family with matching pin configurations and electrical parameters. Verify that alternative part numbers support the same output formats and frequency plans. Consult Skyworks Solutions for custom versions if exact frequency matches are unavailable.

FAQ
