SI5335D-B05883-GMR

Overview

The Skyworks SI5335D-B05883-GMR is a web-customizable, any-frequency, any-output quad clock generator and buffer. 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 configurable as LVPECL, LVDS, CML, HCSL, CMOS, or SSTL/HSTL with independent voltage levels 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 independent output banks supporting any frequency (< 350 MHz) with 0 ppm synthesis error via MultiSynth technology
• Three user-assignable, pin-selectable device configurations for replacing multiple clock ICs
• Flexible input options: External crystal (25/27 MHz), CMOS (10–200 MHz), SSTL/HSTL, or Differential (10–350 MHz)
• Configurable output drivers: LVPECL/LVDS/CML (1–350 MHz), HCSL (1–250 MHz), CMOS (1–200 MHz), SSTL/HSTL (1–350 MHz)

Applications

• PCI Express Gen 1/2/3/4 common clock and jitter attenuation
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• DSL jitter attenuation and MSAN/DSLAM/PON systems
• Processor and FPGA clocking in telecom line cards

Procurement Notes

Verify the specific factory configuration encoded in the B05883 suffix against system requirements using the ClockBuilder Pro utility. Confirm package type is 24-QFN and check RoHS compliance status. As this is a custom-configured part, lead times and availability depend on Skyworks production schedules rather than standard stock levels.

Selection Notes

Select this model when four distinct, non-integer-related clock frequencies are required from a single device. Ensure the input reference matches the supported formats (Crystal, CMOS, or Differential). Verify that the required output voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) align with the load requirements. Use the ClockBuilder Pro tool to generate the unique configuration file for the B05883 variant.

Part Context

This component belongs to the Si5335 family of highly flexible clock generators. The 'D' in the part number typically denotes a specific package or thermal variant within the series, while 'GMR' indicates tape-and-reel packaging. It serves as a drop-in replacement for multiple discrete oscillators and buffers in complex digital systems requiring precise timing.

Replacement Considerations

Direct functional replacements require identical MultiSynth configurations. Check Skyworks documentation for equivalent parts with similar I/O counts and frequency ranges. Ensure pin compatibility if substituting with other Si5335 variants, as internal configuration differences may affect electrical performance.
