The TUSB1211A1ZRQR device 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 TUSB1211A1ZRQR also supports a UART mode and legacy ULPI serial modes.
The TUSB1211A1ZRQR device supports the OTG (Ver1.3) optional addendum to the USB 2.0 Specification, including Host Negotiation Protocol (HNP) and Session Request Protocol (SRP). TUSB1211A1ZRQR also supports USB Battery Charging Specification Ver1.1 integrating a charger detection module for sensing and control on DP/DM lines, and ACA (Accessory Charger Adapter) detection and control on ID line.
The DP/DM external component compensation in the transmitter compensates for variations in the series impendence to match with the data line impedance and the receiver input impedance, to limit data reflections and, thereby, improve eye diagrams.
