SI5335D-B06073-GMR

Overview

The SI5335D-B06073-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 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 typical in clock generator mode.
• Flexible input options including 25/27 MHz crystals, CMOS (10-200 MHz), and differential/SSTL/HSTL (up to 350 MHz).

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 ordering suffix B06073 against the system requirements using the ClockBuilder Pro utility. Confirm that the -GMR suffix indicates tape-and-reel packaging suitable for automated assembly. Ensure the selected loop bandwidth and output formats match the target application's jitter and voltage specifications.

Selection Notes

Select this component when four distinct, non-integer-related clock frequencies are required from a single device. Choose between the 1.6 MHz and 475 kHz PLL loop bandwidth settings based on whether jitter attenuation or fast lock time is prioritized. Ensure the output driver voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) match the receiving logic families. Verify compatibility with PCIe spread spectrum requirements if applicable.

Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' variant typically denotes specific electrical or package characteristics within the series, while the alphanumeric suffix defines the custom frequency plan and pin configuration generated via Skyworks' web-based tool. It serves as a drop-in replacement for multiple discrete oscillators and buffers in complex digital systems.

Replacement Considerations

Direct functional replacements within the same family include other Si5335 variants with different ordering suffixes that match the required frequency plan. For generic buffering needs without frequency synthesis, consider the Si5338 or Si534x series, though these may lack the specific multi-frequency synthesis capabilities of the Si5335.
