SI5335D-B05883-GM

Overview

The SI5335D-B05883-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 flexible input references including external crystals (25/27 MHz), CMOS, SSTL/HSTL, and differential inputs. It features independently configurable outputs supporting LVPECL, LVDS, CML, HCSL, CMOS, and SSTL/HSTL formats with selectable supply voltages of 1.5, 1.8, 2.5, or 3.3 V. The core operates on a single supply of 1.8, 2.5, or 3.3 V.

Feature Summary

• Four independent output banks capable of generating any frequency up to 350 MHz with 0 ppm synthesis error.
• Supports three independent, pin-selectable device configurations for replacing multiple clock ICs.
• Low phase jitter performance of 0.7 ps RMS in clock generator mode.
• Flexible input options including crystal, CMOS, SSTL/HSTL, and differential signals.

Applications

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

Procurement Notes

Verify the specific factory configuration encoded in the B05883 suffix via the official datasheet or ClockBuilder Pro utility. Confirm that the required pin assignments for spread spectrum control, reset, and frequency select match the system design requirements before procurement.

Selection Notes

Select this component when a single device must replace multiple fixed-frequency oscillators or buffers. Ensure the target application requires frequencies up to 350 MHz and benefits from pin-selectable configuration changes. Verify that the available input reference types (crystal vs. digital) align with the system architecture.
