Hi-Speed USB Host, Device or OTG PHY With UTMI+ Interface
DESCRIPTION
D- pin of the USB cable.
PHY ground.
3.3V PHY Supply.
Transceiver Select. These signals select between
the FS and HS transceivers:
Transceiver select.
00: HS
01: FS
10: LS
11: LS data, FS rise/fall times
Charge VBUS through a resistor to VDD3.3.
0: do not charge VBUS
1: charge VBUS
Receive Active. Indicates that the receive state
machine has detected Start of Packet and is active.
Operational Mode. These signals select between
the various operational modes:

ID Digital. Indicates the state of the ID pin.
0: connected plug is a mini-A
1: connected plug is a mini-B
ID Pull-up. Enables sampling of the analog ID line.
Disabling the ID line sampler will reduce PHY power
consumption.
0: Disable sampling of ID line.
1: Enable sampling of ID line.
PHY ground.
60MHz reference clock output. All UTMI+ signals are
driven synchronous to this clock.
PHY ground.
Line State. These signals reflect the current state of
the USB data bus in FS mode. Bit [0] reflects the
state of DP and bit [1] reflects the state of DM. When
the device is suspended or resuming from a
suspended state, the signals are combinatorial.
Otherwise, the signals are synchronized to CLKOUT.

1.8V regulator output for digital circuitry on chip.
Place a 0.1uF capacitor near this pin and connect
the capacitor from this pin to ground. Connect pin 27
to pin 49.
