Dual Port SuperSpeed USB 3.0 Redriver

PTN36242L No Longer Manufactured
  • This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.

The PTN36242L is a dual port SuperSpeed USB 3.0 redriver IC that enhances signal quality by performing receive equalization on the deteriorated input signal followed by transmit de-emphasis maximizing system link performance. With its superior differential signal conditioning and enhancement capability, the device delivers significant flexibility and performance scaling for various systems with different PCB trace and cable channel conditions and still benefit from optimum power consumption.

The PTN36242L is a dual port device that supports data signaling rate of 5 Gbit/s through each channel. PTN36242L has four channels (two ports): one port has two channels. Port 1 has A1 and B1 channels and Port 2 has A2 and B2 channels. The data flow of one channel is facing the USB host and another channel is facing the USB peripheral or device. Each channel consists of a high-speed Transmit (Tx) differential lane and a high-speed Receive (Rx) differential lane.

The PTN36242L has built-in advanced power management capability that enables significant power saving under various different USB 3.0 Low-power modes (U2/U3). It detects LFPS signaling and link electrical conditions and can dynamically activate/de-activate internal circuitry and logic. The device performs these actions without host software intervention and conserves power.

The PTN36242L is powered from a 3.3 V supply and it is available in HVQFN32 3 mm x 6 mm x 0.85 mm package with 0.4 mm pitch.

Features

  • Supports USB 3.0 specification (SuperSpeed only)
  • Support of two ports (Port 1 has A1 and B1 channels; Port 2 has A2 and B2 channels)
  • Each channel supports a receive equalizer and a transmit de-emphasis function
  • Selectable receive equalization on each channel to recover from InterSymbol Interference (ISI) and high-frequency losses, with the ability to choose equalization gain settings per channel
  • Selectable transmit de-emphasis and output swing on each channel delivers pre-compensation suited to channel conditions
  • Integrated termination resistors provide impedance matching on both transmit and receive paths
  • Automatic receiver termination indication and detection
  • Low active power: 743 mW/225 mA (typical) for both ports with Vos = 1000 mV; equalization = 6 dB; de-emphasis = -3.5 dB and VDD = 3.3 V
  • Power-saving states:
    • 60 mW/20 mA (typical) when in U2/U3 states
    • 26 mW/8 mA (typical) when no connection detected
    • 0.5 mW/150 µA (typical) when in deep power-saving state
  • Hot plug capable
  • Power supply: 3.3 V ± 10 %
  • HVQFN32 3 mm x 6 mm x 0.85 mm package with 0.4 mm pitch, exposed center pad for thermal relief and electrical ground
  • ESD: 8 kV HBM, 1 kV CDM for high-speed pins
  • Operating temperature range: 0 °C to 85 °C
