3 說(shuō)明
TUSB8040A1 是一款符合 USB 3.0 標(biāo)準(zhǔn)的四端口集線器，采用 100 引腳 WQFN 封裝。此器件被設(shè)計(jì)用于 0°C 至 70°C 商用溫度范圍內(nèi)的運(yùn)行。
TUSB8040A1 在上行端口上可提供同步超快速 USB 和高速或全速連接，在下行端口上可提供超快速 USB、高速、全速或者低速連接。當(dāng)上行端口被連接到一個(gè)只支持高速、全速或低速連接的電氣環(huán)境中時(shí)，下行端口上的超快速 USB 連接被禁用。當(dāng)上行端口被連接到一個(gè)只支持全速或低速連接的電氣環(huán)境中時(shí)，下行端口上的超快速 USB 和高速連接被禁用。
TUSB8040A1 支持多達(dá)四個(gè)下行端口?？赏ㄟ^(guò)引腳選擇或者通過(guò)連接 EEPROM 或 SMBus 控制器將器件配置為報(bào)告一個(gè)至四個(gè)下行端口。這些配置選項(xiàng)能夠根據(jù)應(yīng)用來(lái)調(diào)整器件。
