Hello support team,

My customer inquires, could you support?

Reference manual SPNU514 Fig 32-96 shows to recommend TUSB1105, can TUSB1106 be used as alternative?

Thanks,

Koji Ikeda.

Hi Koji Ikeda,

No you cant use TUSB1106 instead of TUSB1105, because TUSB1106 supports only differential mode but here we are operating TUSB1105 in single ended mode(by grounding Mode pin of TUSB1105). This is basically because of RM46L852 USB host controller only supports single-ended output mode. So please use only TUSB1105.

See below highlighted information of the datasheet
