Skyworks Solutions, Inc. Integrated Circuits (ICs) - Clock-Timing - Clock Generators, PLLs, Frequency Synthesizers SI5344A-B03540-GM

The SI5344A-B03540-GM is a clock generator that features four input clocks and four output clocks, housed in a 44-QFN package measuring 7x7 mm. It operates within a temperature range of -40 to +85 °C and is compliant with RoHS standards. This device is capable of generating output frequencies from 0.001 MHz to 1028 MHz, supporting both integer and fractional frequency synthesis modes. The SI5344A offers ultra-low jitter performance of 90 fs rms and supports a wide input frequency range of 8 kHz to 750 MHz for differential signals and 8 kHz to 250 MHz for LVCMOS signals. It includes programmable jitter attenuation bandwidth from 0.1 Hz to 4 kHz, making it suitable for applications requiring precise clock generation and jitter management. The device supports various output configurations compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL, with programmable signal amplitude. It features hitless input clock switching, free-run and holdover modes, and is programmable via I²C or SPI interfaces. The ClockBuilder Pro software simplifies device configuration, allowing for easy customization and programming. Applications for the SI5344A include networking line cards, synchronous Ethernet, and broadcast video, making it a versatile choice for engineers seeking reliable clock generation solutions.
