7.1 Overview

The TUSB1004 is a 10 Gbps USB 3.2 quad channel linear redriver for USB Type-A applications. The TUSB1004 is intended to reside between a Host and a USB receptacle or between a USB device and a USB receptacle. The TUSB1004 supports both USB 3.2 Gen2 (10 Gbps) and Gen1 (5 Gbps) as well as USB 3.2 low power states (Disconnect, U1, U2, and U3).

The TUSB1004 supports up to 16 receiver equalization settings controlled by either pin-strap pins or through I2C registers. The USB connector facing receivers (CRX1 and CRX2) support three equalization modes: Fixed EQ, Fast AEQ, and Full AEQ. Selection between these modes is done through either pin-strap pins or through I2C regisrers. The other receivers (SSTX1/2) only support Fixed EQ.

The TUSB1004 operates as a linear redriver for signals traversing from the SSTX1/2 receivers towards CTX1/2 transmitters. It can operate as either a linear redriver or limited redriver for signals traversing from CRX1/2 receivers towards SSRX1/2 transmitters. TUSB1004 defaults to linear redriver but can be enabled for limited redriver by I2C register. When enabled for limited redriver, the SSRX1/2 transmitter support four levels of pre-shoot and four-levels of de-emphasis.
