CY7C68000
TX2™ USB 2.0 UTMI Transceiver
1.0 EZ-USB TX2 Features
The Cypress EZ-USB TX2 is a Universal Serial Bus (USB) specification revision 2.0 transceiver, serial/deserializer, to a parallel interface of either 16 bits at 30 MHz or eight bits at 60 MHz. The TX2 provides a high-speed physical layer interface that operates at the maximum allowable USB 2.0 bandwidth. This allows the system designer to keep the complex highspeed analog USB components external to the digital ASIC which decreases development time and associated risk. A standard interface is provided that is USB 2.0-certified and is compliant with Transceiver Macrocell Interface (UTMI) specification version 1.05 dated 3/29/01. Two packages are defined for the family: 56-pin SSOP and 56pin QFN.
