PRODUCT FEATURES

GT3200

(64-PIN TQFP PACKAGES)

USB3250

(56-PIN QFN PACKAGE)

USB2.0 PHY IC

USB-IF "Hi-Speed" certified to USB2.0 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

Ω and 1.5kΩ 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 USB2.0

specification

Draws 72mA (185mW) maximum current

consumption in HS mode - ideal for bus powered

functions

On-die decoupling capacitance and isolation for

immunity to digital switching noise

Available in three 64-pin TQFP packages (GT3200)

or a 56-pin QFN package (USB3250)

Full industrial operating temperature range from

-40oC to +85oC (ambient)
