SI5345A-B05360-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345A-B05360-GM is a factory preprogrammed, 10-output jitter attenuator and clock multiplier from the Si5345 family. It utilizes fourth-generation DSPLL and MultiSynth technologies to generate any combination of output frequencies from any input frequency. The device supports integer and fractional synthesis modes with an output frequency range up to 1028 MHz for differential outputs. It features ultra-low jitter performance of 90 fs rms and includes in-circuit programmable non-volatile memory (NVM) for configuration storage. The component operates within a temperature range of –40 to +85 °C and is housed in a 64-QFN package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the suffix B05360, as this unique numerical sequence defines the internal frequency plan. Confirm that the ordering part number matches the required Rev D datasheet specifications. Ensure compatibility with the ClockBuilder Pro software for any necessary post-installation adjustments or verification of the NVM data.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when high-performance jitter attenuation is required for multi-output clocking applications. The Si5345A variant supports output frequencies up to 1028 MHz, suitable for high-speed serial links. Verify that the application requires the 10-output configuration and 64-QFN package. Consider the need for factory preprogramming if on-board configuration via serial interface is not desired during initial deployment.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D family of jitter attenuators. The Si5345 model specifically provides four inputs and ten outputs in a 64-QFN package. The 'A' designation indicates support for integer and fractional synthesis modes with extended output frequency ranges compared to lower-tier variants like the 'B' or 'D' models.
