NXP with USB 3.0 SuperSpeed Redriver

As computing systems become faster, signal integrity tends to deteriorate more rapidly than in slower systems. The PTN36241B redriver provides signal equalization on a weakened signal, followed by transmit de-emphasis, thus maximizing link performance, enhancing signal integrity and improving system reliability. To support applications that require a greater level of configurability, the PTN36241B redriver delivers intelligent multiplexing of the I2C-bus interface with quinary (5-level) pins for unmatched flexibility. The PTN36241B redriver supports auto-compliant technology that will enable compliance testing, controlled by the internal state machine, eliminating the need for a separate hardware compliance pin. Technical Features:

“USB 3.0 is 10 times faster than USB 2.0, but a major drawback has been a corresponding loss of signal integrity over longer cable lengths. To compensate for a long trace between the USB 3.0 controller and connector, it is becoming more common to require a redriver, particularly as manufacturers such as Intel start to integrate USB3 directly into the chipset,” said Grahame Cooney, general manager, High Speed Interface product line, NXP Semiconductors.
