NXP Introduces USB 3.0 SuperSpeed Redriver

PTN36241B Supports 5Gbps per Channel With Richest Feature Set in the Market

EINDHOVEN, NETHERLANDS and SAN JOSE, CA--(Marketwire - Sep 12, 2011) - NXP Semiconductors (NASDAQ: NXPI) today announced the release of a breakthrough USB3.0 SuperSpeed redriver, the PTN36241B -- a dual-channel device that supports 5 Gbps per channel with optional settings 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. NXP will showcase the PTN36241B at the Intel Developer Forum (IDF) in San Francisco, California this week (booth 730).

Technical Features:

  • Supports USB3.0 SuperSpeed at 5 Gbps
  • Intelligent I2C-bus multiplexing quinary (5-level) logic configuration options delivering ultimate flexibility
  • Signal integrity enhancements compensate for high frequency losses and inter-symbol interference
  • 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
  • 3.3-V power supply
  • Available in a HVQFN24 4-mm x 4-mm package with 0.5-mm pitch

Supporting Quote

  • "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. 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.

Availability and Pricing

  • The NXP PTN36241B redriver is available immediately, and will be shown this week at IDF 2011 in San Francisco, California.
  • Pricing is contingent on volume, starting at $1.00 for quantities under 1,000.
