SI5335D-B05295-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335D-B05295-GM 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, ensuring 0 ppm frequency synthesis error. The device supports 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 voltage levels of 1.5, 1.8, 2.5, or 3.3 V. It features three pin-selectable device configurations, loss-of-signal alarm, and two selectable PLL loop bandwidths (1.6 MHz or 475 kHz) for jitter attenuation.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the B05295 suffix via the official datasheet or ClockBuilder Pro tool, as this determines the exact input/output frequencies and control pin assignments. Confirm availability status directly with Skyworks Solutions or authorized distributors, as lead times may vary for customized parts.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with low jitter performance. Ensure the input reference matches the supported types (crystal, CMOS, or differential). Verify that the required output voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) align with the target receivers. Use the ClockBuilder Pro utility to define the specific frequency plan and pin controls before ordering.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SI5335D-B05295-GM belongs to the Si5335 family of highly flexible clock generators. The 'D' suffix typically denotes a specific package or temperature range variant within the series, while 'GM' indicates RoHS compliance and tape-and-reel packaging. This part replaces multiple discrete clock oscillators and buffers, simplifying PCB layout and reducing power consumption in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-to-pin replacements require identical frequency plans and control pin mappings. Generic Si5335 variants may differ in output frequencies or pin functions. Verify compatibility with the Si5335A or Si5335B families only if the specific B05295 configuration can be replicated or if system requirements allow for reconfiguration via different control pins.
