SI5345B-B07024-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345B-B07024-GM is a clock synthesizer and jitter cleaner from Skyworks Solutions, belonging to the Si5345 Rev D family. It features four inputs and ten outputs housed in a 64-QFN package measuring 9x9 mm. The device supports integer and fractional frequency synthesis with an output frequency range of 0.001 MHz to 350 MHz. It operates on a core voltage (VDD) of 1.8 V ±5% and an auxiliary voltage (VDDA) of 3.3 V ±5%. The operating temperature range is -40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Combines fourth-generation DSPLL and MultiSynth technologies for any-frequency clock generation and jitter attenuation.
• Includes in-circuit programmable non-volatile memory (NVM) to ensure known frequency configuration upon power-up.
• Supports free-run, synchronous, and holdover modes with automatic or manual input clock switching capabilities.

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

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering part number against the manufacturer's current documentation to confirm availability and revision status. Factory preprogrammed devices utilize unique numerical sequences assigned by Skyworks. Confirm that the B suffix corresponds to the specified 350 MHz output frequency limit and that the GM suffix indicates the standard tube packaging option for this variant.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when applications require up to ten low-jitter outputs derived from various input sources within the 350 MHz range. Ensure the design accommodates the 64-QFN 9x9 mm footprint and provides separate supply rails for VDD and VDDA. Utilize ClockBuilder Pro software for configuration if custom factory programming is not required, as the device supports serial interface programming via I2C or SPI.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This model belongs to the Si5345 Rev D series, which integrates DSPLL and MultiSynth technologies. The 'B' designation specifies the 350 MHz maximum output frequency capability, distinguishing it from the 'A' and 'C' variants that support frequencies up to 1028 MHz. The device is designed for high-performance jitter attenuation in telecommunications and networking infrastructure.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Compatible substitutes include other Si5345B-D-GM variants with different factory preprogramming sequences. Devices such as SI5345B-D-GMR offer tape and reel packaging options instead of tubes. Higher performance models like SI5345A-D-GM provide extended frequency ranges but may require design adjustments.
