Product data sheet
1. General description
PTN36241B is a 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.
PTN36241B is a dual-channel device that supports data signaling rate of 5 Gbit/s through
each channel. PTN36241B has two channels: 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.
PTN36241B has independent 5-level configuration pins for each channel to select receive
equalization, transmit de-emphasis and output swing and these pins can be easily
configured by board-strapping (for example, short, open, resistor). To support applications
that require greater level of configurability, PTN36241B delivers intelligent multiplexing of
I2C-bus interface onto 5-level configuration pins. By default, the device is configured with
the board-strapped levels of configuration pins. When I2C-bus reads/writes are performed
over these multiplexed pins, the device decodes I2C transactions and configures its
internal functions appropriately.
PTN36241B has built-in advanced power management capability that enables significant
power savings under various different USB 3.0 Low-power modes (U2/U3). It can detect
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.
PTN36241B goes through the compliance testing controlled by the internal state machine.
No compliance pin is required.
PTN36241B is powered from 3.3 V supply and is available in HVQFN24 4 mm 4 mm
package with 0.5 mm pitch.
