SI5334B-B04153-GMR

Overview

The SI5334B-B04153-GMR is a pin-controlled, low-jitter clock generator from Skyworks Solutions. It synthesizes any frequency on four differential outputs using MultiSynth technology, supporting frequencies up to 350 MHz generally and select frequencies up to 710 MHz. The device accepts external crystals (8–30 MHz) or reference clocks (5–710 MHz). It features independently configurable output drivers for LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V. The core operates at 1.8, 2.5, or 3.3 V. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum input frequency of 710 MHz, and an operating temperature range of –40 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 voltage levels per driver.
• Low Jitter Performance: Achieves typical phase jitter of 0.7 ps RMS across the operating temperature range.
• Pin-Controlled Configuration: Factory-programmed NVM allows operation without user intervention upon power-up.

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 ordering suffix B04153 against the manufacturer's current documentation to confirm the exact frequency plan and configuration. As this is a custom factory-programmed part, availability may be limited compared to standard off-the-shelf variants. Ensure the package type matches the design requirements, as the Si5334 series utilizes a 24-lead QFN form factor.

Selection Notes

Select this component when pin control is preferred over I2C interfaces for clock generation. Ensure the required output frequencies fall within the 350 MHz general limit or the 710 MHz selective limit. Verify that the target application supports the available output voltage levels (1.5V to 3.3V) and signal formats. Consider the thermal characteristics, with a junction-to-ambient resistance of 37 °C/W in still air, for PCB layout planning.

Part Context

This part belongs to the Si5334 family of quad clock generators. The 'B' suffix typically denotes specific pin-control configurations or feature sets within the series, such as phase increment/decrement capabilities. The 'GMR' suffix indicates the tape-and-reel packaging format suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements must match the 24-QFN package and pinout. Other Si5334 variants (e.g., Si5334C) may serve as functional substitutes if their pin-control schemes and frequency plans align with the system requirements. Verify compatibility with existing firmware or hardware control lines.
