PS8520 – SATA 6Gb/s Repeater
– Not For New Designs –
SATA 6Gb/s Bidirectional Repeater
PS8520A and PS8520B are bidirectional SATA repeaters that support the new SATA 6Gb/s standard, twice the speed of the previous generation SATA. As repeater (or redriver) devices they integrate two equalizer-driver channels to recondition the high-speed SATA signals. In a typically application, the PS8520A or PS8520B is placed close to an eSATA receptacle to compensate for board losses and regenerate high-quality SATA electrical signals.
