Frequently Asked Questions
What is the maximum data throughput of TUSB8042AIRGCT and how many downstream USB ports does it support?
The TUSB8042AIRGCT supports USB 3.2 Gen 1 SuperSpeed with a maximum data transfer rate of 625 MBps across its downstream ports. The device is a 4-port hub controller, allowing simultaneous connection of up to 4 USB 3.2 devices to a single USB host. Each port shares the SuperSpeed upstream bandwidth, so peak per-port throughput is limited by total bus utilization in multi-device scenarios.
How does the I2C/SMBus interface on TUSB8042AIRGCT simplify per-port power management in a docking station design?
The integrated I2C and SMBus interface on TUSB8042AIRGCT allows a system microcontroller to read per-port over-current flags and control per-port power enable signals over a 2-wire bus. This eliminates the need for discrete port-power management ICs, reducing BOM by at least 4 components in a 4-port design. The SMBus compatibility also enables standardized host communication at up to 400 kHz for reading device status and configuring port behavior in embedded docking station and industrial panel PC designs.
What PCB footprint does the 64-pin QFN package of TUSB8042AIRGCT require compared to a TQFP-64 alternative?
The TUSB8042AIRGCT QFN-64 package (S-PQCC-N64) has a 0.35 mm pin pitch with an exposed thermal pad, occupying approximately 49 mm² of board area. A typical TQFP-64 at 0.5 mm pitch occupies about 160 mm² including leads. The QFN's smaller footprint reduces the PCB area by roughly 70%, which is significant in compact docking station PCBs and USB 3.2 hub reference designs where space is at a premium.
