SI5335D-B06047-GM

Overview

The SI5335D-B06047-GM 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 fractional divider technology, ensuring 0 ppm frequency synthesis error. The device supports three independent pin-selectable configurations and features flexible input references including external crystals (25/27 MHz), CMOS, SSTL/HSTL, and differential inputs. Outputs are independently configurable for LVPECL, LVDS, CML, HCSL, CMOS, or SSTL/HSTL formats with selectable supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a single core supply of 1.8, 2.5, or 3.3 V within an ambient temperature range of –40 to +85 °C.

Feature Summary

• Four-output clock generator/buffer synthesizing any frequency up to 350 MHz with 0 ppm error
• Three independent, user-assignable, pin-selectable device configurations
• Flexible input support: External crystal, CMOS, SSTL/HSTL, and differential signals
• Independently configurable outputs supporting LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL

Applications

• PCI Express Gen 1/2/3/4 common clock and jitter attenuation
• Ethernet switch/router and 1 GbE/10 GbE systems
• DSL jitter attenuation and MSAN/DSLAM/PON applications
• Processor and FPGA clocking
• Broadcast video/audio timing and Fibre Channel/SAN

Procurement Notes

Verify the specific factory configuration encoded in the B06047 suffix against system requirements. Confirm that the required input reference type and output voltage levels match the pre-programmed settings. Ensure the 24-QFN package land pattern adheres to the recommended PCB layout guidelines for thermal and electrical performance.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with zero ppm synthesis error. Choose between the 1.6 MHz or 475 kHz loop bandwidth based on jitter attenuation needs for PCIe or DSL applications. Verify that the available pin-selectable control functions (SSENB, RESET, OEB, FS) align with the system's hardware control scheme.

Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' variant typically denotes specific performance or feature sets within the series, while the alphanumeric suffix defines the unique factory programming. It serves as a replacement for multiple discrete oscillators and buffers in complex digital systems.
