NXP PTN36242LBS dual port SuperSpeed USB 3.0 redriver

The PTN36242L is a dual port SuperSpeed USB 3.0 redriver IC.

It enhances signal quality by performing receive equalization on the deteriorated input signal followed by transmit de-emphasis maximizing system link performance.

Key features

• High speed
• USB 3.0 compliant
• 2 ports support
• 3 Power-saving states

Additional 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

Applications

• USB High Speed interfaces
