Si53340-45 LVDS Fanout Clock Buffers Skyworks Solutions Inc. Si53340-45 LVDS Fanout Clock Buffers are optimized for clock/data distribution and redundant clocking applications. The Si53340-45 Buffers provide a typical ultra-low jitter of 50fs and operate over a wide DC to 1250MHz frequency range. These devices feature minimal cross-talk and offer superior supply noise rejection, simplifying low jitter clock distribution in noisy environments. Independent core and output bank supply pins provide integrated level translation without the need for external circuitry.
