USB2.0 PHY IC
PRODUCT FEATURES
Datasheet
„ 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 45Ω 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
-40^oC to +85^oC (ambient)
