Si5336x LVCMOS Fanout Clock Buffers Skyworks Solutions Inc. Si5336x LVCMOS Fanout Clock Buffers are ideal for clock/data distribution and redundant clocking applications. The buffers utilize Skyworks' advanced CMOS technology to fan out clocks from dc to 200MHz. The Si5336x family features guaranteed low additive jitter, low skew, and low propagation delay variability. Built-in LDOs deliver high PSRR performance and eliminates the need for external components simplifying low jitter clock distribution in noisy environments.
