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.
