TUSB2046B: Single or Multi Transaction Translator?

Victor Miranda

Part Number: TUSB2046B

Hi,

I am designing an USB hub with TUSB2046B to be used with Raspberry Pi, and "It is recommended to use a Multi-TT hub to interface with multiple lower-speed devices."

Please refer to: https://www.raspberrypi.org/documentation/hardware/raspberrypi/usb/README.md

The question is if TUSB2046B is a single-TT or multi-TT hub device?

Best regards,

Victor Miranda

Neither, the TUSB2046B is a full speed hub so it has no transaction translators. The TUSB4041 or TUSB4020B are high speed USB hubs with multi TT support, either of those would probably be a better fit for the application.
