SI5341B-B05580-GM is listed in the Clock Generators, PLLs, Frequency Synthesizers range at ChipApex. The manufacturer field lists Skyworks Solutions Inc.. Its product description is IC CLOCK GENERATOR PLL. Review the specifications below when checking this part for your BOM.
The SI5341B-B05580-GM is a programmable clock generator from the Si5341 series by Skyworks Solutions. It features 10 outputs and supports any-frequency synthesis up to 350 MHz on differential outputs. Key electrical parameters include an input frequency range of 10 to 750 MHz for differential clocks, output formats including LVDS, LVPECL, LVCMOS, CML, and HCSL, and ultra-low jitter performance of 90 fs rms. The device operates within a supply voltage range of 1.71 V to 3.47 V, with typical operating currents of 115 mA or 120 mA. It is housed in a QFN-64 package (9x9 mm) and functions within a temperature range of -40°C to +85°C.
Verify availability status as this specific suffix may be subject to limited supply or end-of-life conditions. Confirm RoHS compliance and moisture sensitivity level before ordering. Ensure compatibility with ClockBuilderPro software for configuration. Check for obsolescence notices from Skyworks Solutions prior to final procurement decisions.
Select this component when sub-100 fs jitter is required across multiple differential outputs. Verify that the 350 MHz maximum output frequency meets system requirements. Ensure the QFN-64 package fits the PCB layout constraints. Consider the need for I2C/SPI programming interfaces if custom frequency plans are necessary.
This part belongs to the Si5341 family, which integrates wide-band PLLs with fractional synthesizers. It replaces multiple discrete oscillators and clock buffers with a single 'clock tree on a chip' solution. The B-suffix typically denotes specific factory-programmed configurations.
SI5341B-D-GM is listed as a similar alternative in public databases for related Si5341 variants.
