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
