The TUSB1210-Q1 is a USB2.0 transceiver chip, designed to interface with a USB controller via a ULPI interface. It 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. It additionally supports a UART mode and legacy ULPI serial modes. TUSB1210-Q1 also supports the OTG (Ver1.3) optional addendum to the USB 2.0 Specification, including Host Negotiation Protocol (HNP) and Session Request Protocol (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.
