MoBL-USB
TX2 Features
UTMI-compliant/USB 2.0 certified for device operation
Operates in both USB 2.0 high-speed (HS),
480 Mbits/second, and full-speed (FS), 12 Mbits/second
Optimized for seamless interface with Intel
Monahans
Applications Processors
Tri-state Mode allows sharing of UTMI bus with other
devices
Serial-to-parallel and parallel-to-serial conversions
8-bit unidirectional, 8-bit bidirectional, or 16-bit bidirectional
external data interface
Synchronous field and EOP detection on receive packets
Synchronous field and EOP generation on transmit packets
Data and clock recovery from the USB serial stream
Bit stuffing/unstuffing; bit stuff error detection
Staging register to manage data rate variation due to bit
stuffing/unstuffing
16-bit 30 MHz and 8-bit 60 MHz parallel interface
Ability to switch between FS and HS terminations and
signaling
Supports detection of USB reset, suspend, and resume
Supports HS identification and detection as defined by the
USB 2.0 Specification
Supports transmission of resume signaling
3.3V operation
Two package options: 56-pin QFN and 56-pin VFBGA
All required terminations, including 1.5 Kohm pull up on
DPLUS, are internal to chip
Supports USB 2.0 test modes
The Cypress MoBL-USB
TX2
is a Universal Serial Bus
(USB) specification revision 2.0 transceiver, serial/deseri-
alizer, 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 allows the system designer
to keep the complex high-speed 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 3/29/2001.
This product is also optimized to seamlessly interface with
Monahans -P & -L applications processors. It has been
characterized by Intel and is recommended as the USB 2.0
UTMI transceiver of choice for its Monahans processors. It is
also capable of tri-stating the UTMI bus while suspended to
allow the bus to be shared with other devices.
Two packages are defined for the family: 56-pin QFN and
56-pin VFBGA.
