SI5345D-B05784-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5345D-B05784-GM is a factory preprogrammed jitter attenuator and clock multiplier from the Si5345 Rev D family. It features four inputs and ten outputs, supporting differential frequencies up to 350 MHz and LVCMOS up to 250 MHz. The device integrates fourth-generation DSPLL and MultiSynth technologies for any-frequency generation with ultra-low jitter of 90 fs rms. It operates on a single 1.8 V core supply (VDD) and independent output supplies (VDDA) ranging from 1.71 V to 3.47 V. The component is housed in a 64-QFN 9x9 mm package and supports an operating temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Generates any combination of output frequencies from any input frequency using integer and fractional synthesis.
Provides hitless input clock switching between fractionally related inputs without phase offset propagation.
Supports free-run, holdover, and locked modes with programmable jitter attenuation bandwidth.
Features highly configurable outputs compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL signal formats.

Clock Generators, PLLs, Frequency Synthesizers Applications

OTN muxponders and transponders
10/40/100 G networking line cards
GbE/10 GbE/100 GbE Synchronous Ethernet (ITU-T G.8262)
Carrier Ethernet switches
SONET/SDH line cards

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the suffix B05784 against the target design requirements. Confirm that the 64-QFN 9x9 mm package dimensions align with the PCB land pattern. Ensure the serial interface protocol matches the system controller capabilities.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a fixed 350 MHz maximum output frequency is sufficient and factory programming is preferred over user configuration. Compare with SI5345A-D variants if higher frequency ranges or fractional-only synthesis are not required. Verify that the integrated loop filter meets the specific jitter attenuation bandwidth needs of the application.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5345 Rev D series, which combines DSPLL and MultiSynth technologies. It is distinct from the Si5344 (4 outputs) and Si5342 (2 outputs) variants within the same family. The 'D' designation indicates the revision level, while the alphanumeric suffix denotes a unique factory-programmed frequency plan.
