NXP Semiconductors has released its latest offering, the PTN36241B redriver. This SuperSpeed redriver is a dual-channel device that can support USB 3.0 connectivity and 5Gbit/s per channel that provide a high level of extendibility.

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.

"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. By providing high signal integrity performance, the PTN36241B helps system engineers and users to overcome these limitations, while offering maximum flexibility to enable use with a diverse range of platforms," said Grahame Cooney, general manager, high speed interface product line, NXP Semiconductors.

Other technical features of the PTN36241B redriver include:

???Selectable output swing, transmit emphasis, receive equalization, and input signal threshold improve device flexibility;

???Rx termination indication and detection enhance Hot Plug capability;

???LFPS detection and forwarding;

???Intelligent Power management with multiple power saving modes reduce power dissipation

???ESD protection: HBM 8 kV, CDM 1 kV

???3.3V power supply

???Available in a HVQFN24 4 4mm package with 0.5mm pitch

Prices of the NXP PTN36241B redriver starts at $1 for quantities under 1,000.
