DescriptionThe Si5365 is a low jitter, precision clock multiplier for high-speed communication systems, including SONET OC-48/OC-192, Ethernet, and Fibre Channel, in which the application requires clock multiplication without jitter attenuation. The Si5365 accepts four clock inputs ranging from 19.44 to 707 MHz and generates five frequency-multiplied clock outputs ranging from 19.44 to 1050 MHz. The input clock frequency and clock multiplication ratio are selectable from a table of popular SONET, Ethernet, and Fibre Channel rates. The Si5365 is based on Silicon Laboratories' 3rdgeneration DSPLL® technology, which provides anyrate frequency synthesis in a highly integrated PLL solution that eliminates the need for external VCXO and loop filter components. The DSPLL loop bandwidth is digitally programmable, providing jitter performance optimization at the application level. Operating from a single 1.8 or 2.5 V supply, the Si5365 is ideal for providing clock multiplication in high performance timing applications.
