TX2 USB UTMI Transceiver

EZ-USB TX2 Features
• 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
that operates at the maximum allowable USB bandwidth.
• Bit stuffing/unstuffing bit stuff error detection

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 dated
• 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

Two packages are defined for the family 56-pin SSOP and 56pin QFN.

The function block diagram is shown in Figure The features of the EX-USB TX2 are:
• Supports detection of USB reset, suspend, and resume
• Supports HS identification and detection as defined by the USB Specification
• Supports transmission of resume signaling
• UTMI-compliant/USB-2.0-certified for device operation
• V operation
• Operates in both USB high speed HS , 480
• Two package QFN, and 56-pin SSOP

Mbits/second, and full speed FS , 12 Mbits/second
• All required terminations, including 1.5K-ohm pull up
• Serial-to-parallel and parallel-to-serial conversions
on DPLUS, are internal to the chip
• 8-bit unidirectional, 8-bit bidirectional, or 16-bit
• Supports USB test modes
bidirectional external data interface

PCB Layout Recommendations[3]
51-85187-*A

The following recommendations should be followed to ensure reliable high-performance operation.
• At least a four-layer impedance controlled boards are required to maintain signal quality.
• Specify impedance targets ask your board vendor what they can achieve .
• To control impedance, maintain trace widths and trace spacing to within specifications.
• Minimize stubs to minimize reflected signals.
• Connections between the USB connector shell and signal ground must be done near the USB connector.
• Bypass/flyback capacitors on VBus, near the connector, are recommended.
• DPLUS and DMINUS trace lengths should be kept to within 2 mm of each other in length, with preferred length of mm.
• Maintain a solid ground plane under the DPLUS and DMINUS traces. Do not allow the plane to be split under these traces.
• If possible, do not place any vias on the DPLUS or DMINUS trace routing.
• Isolate the DPLUS and DMINUS traces from all other signal traces by no less than 10 mm.
