SI5335D-B05194-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335D-B05194-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 the -40 to +85 °C temperature range.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix B05194 against the official Skyworks datasheet to confirm the exact frequency plan and configuration. As a factory-customized part, lead times and availability may vary significantly from standard inventory items. Confirm RoHS compliance and moisture sensitivity level requirements prior to procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component 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 utility to define the specific frequency plan before ordering.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'D' suffix typically denotes a specific package or 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 clock distribution.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 24-QFN package and support four outputs. Verify that substitute devices offer comparable jitter performance and support the required output formats (LVPECL/LVDS/CML/HCSL/CMOS/SSTL). Check if the alternative supports the same input reference types and pin-selectable configuration capabilities.
