SI5335B-B06032-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335B-B06032-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 technology for 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. Key electrical parameters include a core supply voltage range of 1.71–3.63 V, operating temperature from –40 to +85 °C, and low phase jitter performance.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific configuration code B06032 against the official Skyworks ClockBuilder Pro tool or datasheet ordering section to ensure correct pin assignments and output formats. Confirm availability status as customized parts may have restricted distribution channels. Validate that the required input reference type matches the device's programmed configuration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four distinct, non-integer-related clock frequencies are required within a single package. Ensure the application supports the Si5335 family's requirement for web-based customization via ClockBuilder Pro. Verify that the target system can accommodate the QFN-24 package dimensions and thermal requirements. Check if the specific output voltage levels needed (1.5V vs 3.3V) align with the load devices.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5335 family of highly flexible clock generators. The 'B' suffix in the part number typically denotes a specific input configuration variant within the family, often related to crystal or reference input types compared to other variants like 'A', 'C', or 'D'. It serves as a drop-in replacement for multiple discrete oscillators and buffers in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-to-pin replacements within the Si5335 family (e.g., SI5335A, SI5335C, SI5335D) may be possible but require verification of the specific input/output configuration codes. Ensure the substitute part supports the same maximum frequency (350 MHz) and output drive strengths. Customization codes must match exactly to maintain functional equivalence.
