USB3250
Hi-Speed USB Device Transceiver with UTMI Interface
Highlights
• USB-IF "Hi-Speed" certified to USB 2.0 electrical
specification
• Interface compliant with the UTMI specification
(60MHz 8-bit unidirectional interface or 30MHz
16-bit bidirectional interface)
• Supports 480Mbps High Speed (HS) and 12Mbps
Full Speed (FS) serial data transmission rates
• Integrated 45 and 1.5k termination resistors
reduce external component count
• Internal short circuit protection of DP and DM
lines
• On-chip oscillator operates with low cost 12MHz
crystal
• Robust and low power digital clock and data
recovery circuit
• SYNC and EOP generation on transmit packets
and detection on receive packets
• NRZI encoding and decoding
• Bit stuffing and unstuffing with error detection
• Supports the USB suspend state, HS detection,
HS Chirp, Reset and Resume
• Support for all test modes defined in the USB 2.0
specification
• Draws 72mA (185mW) maximum current con-
sumption in HS mode - ideal for bus powered
functions
• On-die decoupling capacitance and isolation for
immunity to digital switching noise
• Available in a 56-pin VQFN package
• Full industrial operating temperature range from
-40oC to +85oC (ambient)
Applications
The Universal Serial Bus (USB) is the preferred inter-
face to connect Hi-Speed PC peripherals.
• Digital Still and Video Cameras
• MP3 Players
• External Hard Drives
• Scanners
• Entertainment Devices
• Printers
• Test and Measurement Systems
• POS Terminals
• Set Top Boxes
