The Cypress MoBL-USB TX2
 is a Universal Serial Bus (USB)
specification revision 2.0 transceiver, serial and deserializer, to a
parallel interface of either 16 bits at 30 MHz or eight bits at 60
MHz. The MoBL-USB TX2 provides a high speed physical layer
interface that operates at the maximum allowable USB 2.0
bandwidth. This enables the system designer to keep the
complex high speed analog USB components external to the
digital ASIC. This decreases development time and associated
risk. A standard USB 2.0-certified interface is provided and is
compliant with Transceiver Macrocell Interface (UTMI) specifi-
cation version 1.05 dated 3/29/2001.
This product is also optimized to seamlessly interface with
Monahans -P & -L applications processors. It has been charac-
terized by Intel and is recommended as the USB 2.0 UTMI trans-
ceiver of choice for its Monahans processors. It is also capable
of tri-stating the UTMI bus, while suspended, to enable the bus
to be shared with other devices.
Two packages are defined for the family: 56-pin QFN and 56-pin
VFBGA.
