7.2.7.2 USB 2.0 OTG PHY
•
•
•
•
•
Complete PHY for USB2.0 On-The-Go
USB 2.0 UTMI+ specification compliant
Supports high speed (480 Mbit/s), full speed (12 Mbit/s) and low speed (1.5 Mbit/s) data transmission
Supports OT supplement features: VBUS state detecting SRP request by “data-line pulsing” method
Low jitter clock from either on-chip PLL (48MHz) or optional additional crystal (12MHz, 24MHz or 48MHz) which is
available with the 224 pin package, only
•
•
16 bit parallel datain/out interface
Typical current consumption on vdda33c and vdd33t:
•
•
•
•
•
12 mA in FS RX mode
30 mA in FS TX mode
30 mA in HS RX mode
40 mA in HS TX mode
< 100 uA in suspend mode
•
Rext = 3.4kOhm (+/- 1%) must be connected between pads “rext” and “vssa33c” to set the bias current.
