Product Overview
The TUSB522P is a Texas Instruments USB 3.1 Gen 1 redriver for 5 Gbps dual-channel, single-lane USB signal-chain use. It operates from a 3.3 V nominal supply, with recommended VCC limits of 3.0 V to 3.6 V, a maximum supply ramp of 100 ms, and maximum VCC supply noise of 100 mV.
Signal conditioning is set through control pins. Receiver equalization supports 3 dB, 6 dB, and 9 dB settings at 2.5 GHz, while output de-emphasis supports 0 dB, -3.5 dB, and -6.2 dB. Output swing is selected as 0.9 mV or 1.1 mV according to the OS1 and OS2 pin functions.
The device is supplied in an RGE 24-pin VQFN package. Thermal data for this package includes 51.2°C/W junction-to-ambient resistance and 9.7°C/W junction-to-case bottom resistance. TUSB522P covers a 0°C to 70°C free-air operating range, while TUSB522PI is specified for -40°C to 85°C.
