SLLSFM9 March 2021 TUSB216I
The TUSB216I is a USB High-Speed (HS) signal conditioner designed to compensate for ISI signal loss in a transmission channel. TUSB216I has a patented design for USB Low Speed (LS) and Full Speed (FS) signals. It does not alter the signal characteristics. HS signals are compensated. The design is compatible with USB On-The-Go (OTG) and Battery Charging (BC) specifications.
Programmable signal gain through an external resistor permits fine tuning device performance to optimize signals. This helps pass USB HS electrical compliance tests at the connector. Additional RX sensitivity, tuned by external pull-up resistor and pull-down resistor, allows to overcome attenuation in cables. The TUSB216I allows application in series to cover longer distances, or high loss transmission paths. A maximum of 4 devices can be daisy-chained.
