Beschreibung von TUSB1210
The TUSB1210 is a USB2.0 transceiver chip, designed to interface with a USB controller through a ULPI interface. The device supports all USB2.0 data rates (high-speed 480 Mbps, full-speed 12 Mbps, and low-speed 1.5 Mbps), and is compliant to both host and peripheral modes. The device additionally supports a UART mode and legacy ULPI serial modes. TUSB1210 also supports the OTG (Ver1.3) optional addendum to the USB 2.0 Specification, including HNP and SRP.
The DP/DM external component compensation in the transmitter compensates for variations in the series impendence in order to match with the data line impedance and the receiver input impedance, to limit data reflections and thereby improve eye diagrams.
