SI5364-F-BC

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5364-F-BC is a SONET/SDH precision port card clock IC designed for ultra-low jitter high-speed clock generation and distribution. It phase locks to one of three reference inputs in the 19.44 MHz range and generates four synchronous clock outputs independently configurable for 19, 155, or 622 MHz operation (1x, 8x, and 32x input clock). Utilizing DSPLL technology, it eliminates external loop filter components while supporting Stratum 3/3E and SMC compatible switching. The device operates from a single 3.3 V supply with an operating temperature range of -20°C to 85°C.
