Texas Instruments Launches New High-speed USB 2.0 On-The-Go Solution

(Product News, 7 Apr 2008)

Texas Instruments Inc. (TI) has released a high-speed Universal Serial Bus (USB) 2.0 On-The-Go (OTG) dual-role controller that provides flexible architecture to meet a multitude of customer-defined applications. It can operate either as a function controller for a USB peripheral or as the host/peripheral in point-to-point or multipoint communications. Featuring an idle mode operating current of only 0.1mA, the device will extend battery life in consumer devices, such as mobile handsets, portable media players or video applications.

The TUSB6020 is a compact solution for space-conscious equipment and comes in a 5x5mm package. It is compliant with the USB 2.0 OTG specification by the USB Implementer's Forum, ensuring interoperability with other USB devices. Its integrated USB 2.0 PHY provides design flexibility with one-port operation at a low speed of 1.5Mbps, full speed of 12Mbps and high speed of 480Mbps. The VLYNQ serial interface allows seamless interface to any VLYNQ-enabled application processor without loading the GPMC or EMIF ports.

Other key features include:
- Uses industry-standard Mentor Graphics USB 2.0 OTG core
- Supports session request protocol and host negotiation protocol
- On-chip integrated 45¦¸ high-speed termination, 1.5k¦¸ pullup, and 15k¦¸ pulldown resistors
- On-chip phase-locked loop to reduce noise on high-speed clocks
- Protection circuitry to withstand possible VBUS short

The TUSB6020 will add high-speed USB capability to any TMS320DM643x DaVinci technology-based product.
