SI5318 General Description
The Si5318 is a precision clock multiplier designed to exceed the requirements of high-speed communication systems, including OC-48. The device phase locks to an input clock in the 19, 39, 78, or 155 MHz frequency range and generates a low jitter output clock in the 19 or 155 MHz range. Silicon Laboratories' DSPLL® technology delivers all PLL functionality with unparalleled performance while eliminating external loop filter components, providing programmable loop parameters, and simplifying design. The Si5318 establishes a new standard in performance and integration for ultra-low-jitter clock generation. It operates from a single 3.3 V supply.
