SI5335D-B06031-GMR

Overview

The SI5335D-B06031-GMR is a web-customizable, any-frequency, any-output quad clock generator and buffer manufactured by Skyworks Solutions. It synthesizes four non-integer-related frequencies up to 350 MHz using MultiSynth technology, ensuring 0 ppm frequency synthesis error. The device features four output banks supporting differential or single-ended configurations with independent voltage levels of 1.5, 1.8, 2.5, or 3.3 V. It operates on a single core supply (1.8, 2.5, or 3.3 V) and supports flexible inputs including external crystals (25/27 MHz), CMOS (up to 200 MHz), and differential/SSTL/HSTL signals (up to 350 MHz).

Feature Summary

• MultiSynth fractional divider technology enables independent synthesis of four frequencies with 0 ppm error.
• Supports three independent, pin-selectable device configurations for system flexibility.
• Low phase jitter performance of 0.7 ps RMS typical in clock generator mode.
• Configurable as a clock generator or buffer with up to four differential or eight single-ended outputs.

Applications

• PCI Express Gen 1/2/3/4 common clock generation
• Ethernet switch and router timing
• DSL jitter attenuation
• Processor and FPGA clocking

Procurement Notes

Verify the specific factory configuration encoded in the B06031 suffix against the design requirements. Confirm that the required input reference type and output formats match the programmed settings. Ensure the PCB land pattern matches the 24-QFN package outline provided in the datasheet. Validate power supply decoupling strategies for the separate VDDO domains.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source without integer division constraints. Choose the appropriate loop bandwidth (1.6 MHz or 475 kHz) based on whether jitter attenuation or fast lock time is prioritized. Ensure the target output voltage levels (LVPECL, LVDS, CML, HCSL, CMOS, SSTL/HSTL) are supported by the available VDDO supplies.

Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' suffix typically denotes specific electrical characteristics or package variations within the series, while the alphanumeric code defines the unique factory-programmed register map. It serves as a replacement for multiple discrete oscillators and buffers in complex digital systems.

Replacement Considerations

Direct pin-to-pin replacements may exist within the Si5335 family (e.g., Si5335A, Si5335B, Si5335C) but require verification of the specific frequency plan and output driver capabilities. Cross-model substitution requires reconfiguration via ClockBuilder Pro if the new part supports the same I2C programmability or pin-selectable modes.
