Skyworks Solutions, Inc. Integrated Circuits (ICs) - Clock-Timing - Clock Generators, PLLs, Frequency Synthesizers SI5342A-B05630-GM

The SI5342A-B05630-GM is a clock generator that features four input clocks and two output clocks, housed in a 44-QFN 7vó7 mm package. It supports a wide output frequency range from 100 Hz to 1028 MHz for differential outputs and up to 250 MHz for LVCMOS outputs. The device is designed for ultra-low jitter performance, with a specified jitter of 90 fs rms. It operates with input frequencies ranging from 8 kHz to 750 MHz for differential inputs and 8 kHz to 250 MHz for LVCMOS inputs. The SI5342A-B05630-GM is highly configurable, supporting various output formats including LVDS, LVPECL, LVCMOS, CML, and HCSL, with programmable signal amplitude. It includes features such as programmable jitter attenuation bandwidth, hitless input clock switching, and free-run and holdover modes. The device is programmable via a serial interface (I²C or SPI) and includes in-circuit programmable non-volatile memory for configuration retention. It operates over a temperature range of -40 to +85 °C and is compliant with RoHS standards. This product is suitable for applications in networking line cards, synchronous Ethernet, and other high-performance clock generation needs.
